    Thank you

    The book was published back in 2016 - (seems like years ago now!) - unfortunately not in time for the Rijeka Torpedo conference.

    Yes the reference material from "La Storia Del Siluro" that you posted enabled me to search for and find a copy that an Italian bookseller had shortly afterwards - it was one of the limited 1982 reprints - haven't seen a copy since. (spend endless hours translating parts of it for the book) Around that time I also track down a copy of the Whitehead Sales Ledger....................

    Unfortunately no soft copy is available - call me "old fashion" as I prefer to have a physical book in hand rather than read a .pdf file any day, which is one of the reasons that it got published!

    PM me if you are still after a copy - there a few left.
    Cheers

    Very good finding, the Motofides reprint from 1982 is defenitely sleek with its slipcase, I do own both (no, I'm not a book maniac..). The sales ledger must come from Petrucci's book, a good friend of mine, keep it private as the Company doesn't want these informations to be proliferated on the net, thats also the reason why there is just the oldest part of the ledger published.

    Thanks mate but between price+shipping+customs I'd end up paying around $75 for it and given the content there is nothing I don't have among my nineteenth century manuals, I just wanted to review it and check if any of the material provided in the past was inserted and aknowledged as I felt that the below thread - among other exchanges - gived their contribute. During the period of your requests about these fuzes and Whitehead/BMAG in general you've never mentioned that the informations were needed in order to publish and sell a book.

    Just a couple of clarifications:

    Yes the material you posted was extracted from the above mentioned book - the quality /resolution wasn't acceptable for a later book publication decision, hence the search for a copy of the book and thereby the potential to obtained higher resolution scans of the diagrams; (None of your posted photos were used in the book else I would have included photo acknowledgements to you)

    The diagrams alone do not provide a sufficient detail description of how some of the more complex mechanisms function, which was absent from your postings - hours of book translation provided that.

    At the time of the postings (May 2014) I did indeed attempted to reach out to you - however I believe due to your work /travelling commitments the communications was slow, infrequent and there were periods of no replies ( I don't even know what your surname is!)

    In addition, I was also seeking a copy of the Whitehead Sales Ledger in which you had access to but reluctant /unable to provide a full copy. (I now have a full copy in addition to Petrucci's Book (English)) You indeed may have an extensive library on torpedo reference books - I now have access to a number of extensive private libraries on torpedo books in addition to my own.

    Finally the decision to publish 3 years of torpedo pistol design research only came about in 2016 prior to the Rijeka Conference and actually suggested by my Wife as a handout to other conference guest if required - I originally never intended to publish the research as it was just for my own amusement. However it started to become very clear that there was a distinct lack of available information on torpedo pistol development /design. The purpose of the book was to capture the chronological order of Whitehead Pistol and provide that in one simple reference rather than having to search /beg /borrow /google in the hope of finding any relevant data as I had to do over 3 years.

    My apologies if you feel that you have been excluded from the book acknowledgements as I did indeed attempted to include all - reaching out to all those that assisted in any way. Perhaps the period of radio silence didn't help when I never heard back from you or me just getting old and forgetful ...........I could rectify that in the next revised edition..............

    Cheers

    Drew I’ve been misunderstood, most likely because of my limited English: I’m not seeking for aknowledgements, if you didn’t felt to be rightly addressed or that the material/informations provided in past here on the forum, by PMs or email was not valuable to your researches purposes I can’t see any reason why you should think that today.
    The acknowledgment I’m on about was referred to the pictures shot by myself and not to the material coming from the manuals/book, which I’m very happy to share with anyone as usual.
    What I meant with the review is that if you’d have told me about your project I’d integrated your research with fuzes missing in your index, addressing you to the manuals, archives and sources where the real juice is held.


    From your words I deduce I’ve offended you with my terrible communication timing and because I didn’t sent you the sales book: about the first I’m very sorry but because of my job I travel very often, sometimes for months in countries where I can’t easly maintain steady communications and of course with no access to personal documentation, about the second nobody is allowed to use the material contained in Petrucci’s outstanding job or coming from the Whitehead private archives without the Company/author allowance.
    “WASS 133 years of history” is not a publication out for sale beacuse is the now days gift of the Company to customers and the archive material which I’m lucky enough to have thanks to my relations with the Company and engineer Petrucci has been asked to keep private; as I’ve only one word, no matter if in a public or private channel I honor my word. I bet that who sent you a copy of the said sales book didn’t.
    Because of the above, I’m the one that apologise to you.


    Back on the net cutting device topic, I’ve to rectify what I wrote about the US made head sawed profile posted before, as I’ve found in the archive the attached picture (NH 84493), referred to trials of the said head and clearly showing a pierced (weak) metal made net, not a hemp fibres one.


    [edit]


    Just quoting your original post, to the which my reply was addressed:

    Yes the material you posted was extracted from the above mentioned book - the quality /resolution wasn't acceptable for a later book publication decision, hence the search for a copy of the book and thereby the potential to obtained higher resolution scans of the diagrams; (None of your posted photos were used in the book else I would have included photo acknowledgements to you)

    My apologies if I have excluded you from the book acknowledgements as I did indeed attempted to include all - perhaps the period of radio silence didn't help or me just getting old and senile...........I'll rectify that in the next revised edition.
    Re the reasons that pushed you to publish your research: a noble and very helpfull purpose that deserves big credit, informations on such old subsystems are difficult to find and being spread over a large time window never clustered together.

    Broswing the valuable pictures collection cantained in the site posted by BDGREEN in this section (digitaltmuseum.se), I've found among the many interesting pieces these odd swedish (?) net cutters devices.

    I have located a reference to what would appear to be Wilson's net cutter as a 'Pioneer' in a discussion over Woolwich torpedo gyroscopes, along with a few other bits and pieces. It's starting to reach the point now where I think I might be able to gather sufficient material to write a small article on the British torpedo net cutter.

    Lefa (4th June) shows pictures originally posted by BDGREEN The middle picture resembles the Wilson "Pioneer", if I remember correctly, if the four blades are replaced by four versions of the last (Open scissor) cutter. Thus there are four vee shaped cutters facing forwards, each carrying a small striker pin, travelling in a small diameter hole formed within the thickness of the blade, as can be seen in the last picture (RHS) I think that there may also have been a central striker, but I do not remember a safety fan. Perhaps, as these net-cutting torps would be launched in a harbour, at close range, by small, rapidly manoeuvring vessels, it was felt that there was no need to protect against a malfunctioning weapon-possibly the gyro might have been locked as well?

    I have a small off topic question because my trip starts shortly. But the knowledge on the torpedo area is the biggest in this topic, I am staying in the neighborhood off Rijeka next week, is there beside the torpedolauncing site (Whitehead factory) any torpedo related material to be seen in Rijeka. The Internet is not clear on this subject. Thanks in advance!
