    120 mm case ID

    I have attached a couple of pictures of a shell case that I am trying to ID. Measurements are 122mm x 252mm x 144mm Rim and it takes a protruding adapter/primer

    The case is marked 120 m/m and made by Vickers (VSM), which normally indicates that it would be made for a foreign contract (possibly Japan) as we did not normally mark cases in metric. The odd thing about this is that it has the British naval ‘N’, broad arrow and typical ‘CF’ markings, which indicate British use. I cannot find any match in the information I have and the case is not cut down.

    Any information or ideas greatly appreciated.

    VSM is Vickers and Sons Maxim. Made in June of 1914. I believe this is one that might take the large external Primer.

    Thanks Tim, that ties in perfectly. The Navweapons site is a great resource, shame I didn't do a proper search on it!

    And so if anyone has a WW1 4.7" HE projectile that they no longer love ...........

    When I check my references for WW1 period shell cases with a rim diameter 143-145 mm I do not get any hit identifying this case. There are some Dutch WW1 period 12 cm navy cases (681 mm or 808 mm long for Krupp L/40 guns) that fit the rim diameter, and although "we" did buy some ammunition from the UK, there are no markings on this case that say it is Dutch used and the only UK bought cases I know of are different ones (Vickers 7,5 cm M1936 AA and Vickers 76,2 mm 13 Pdr. 9 CWT II for UK guns). I also expect it to be intended as export and used by the UK, so TimG might be onto something here. For me, this is an unknown case. Nice one, thanks for sharing!

    So originally there was a fixed cartridge which was shortened to achieve seperate loading....

    Hi Daniel ...
    Having just read the entire section on German WW1 mines (a subject about which i knew nothing), i can offer no easy answer.. Very few illustrations of them. They seemed to be either hemispherical at top and bottom with a cylindrical mid section ... or similar but with a coned bottom.
    And the Trademe example was basically spherical..
    Will email you photos of the pages

    Thanks Charley. Co-incidentally I've just ordered a book by Ian Buxton on the Monitors, so I'll update this thread if there is any other useful information in it.

    thanks for the info charley,he states in the book that all ww1 german mines were thought to have hertz horns,so this one and others washed up in NZ must be either pre 1915 or a undescribed/unknown type
