Kynoch cartridge box date codes & colour band

[Rrickoshae]

hi, I wonder if anyone can tell me how to work out date codes for the buff colour Kynoch boxes? See attached examples, the .30 Rimless box has a code of 17 R G and the 6.5mm mannlicher has what appears to be 9 D F and a red band. Any thoughts?

many thanks, Dave

The book "The Birmingham Cartridge Manufacturers" states .30-06 Springfield as listed by Kynoch 1925-1970, and 6.5mm x 53R Mannlicher as listed by Kynoch 1897-1970.

Lew Curtis from the IAA put together a document collating info that appeared in IAA Journals 442 and 449 relating to a set of date codes used by Eley and two sets of date codes used by Kynoch. I think the document has appeared on the internet but I cannot find the link. The title was Kynoch 9x19 Box Styles.

Kynoch used a number-letter-letter code from 1911-1926 indicating day-month-year
The month code letters used from 1911 and later were based on the code word KYNOIDCARTGS K indicating January, etc.
The year code letters from 1911-1916 were based on the word KYNOCH
The year code letters from 1917-1928 were going to be based on KYNOCHPRIMAX, but in 1926 a new number system was introduced using the ABC alphabet starting at A so the last letters of the code were not used.

If my understanding of these codes is correct, 17 R G would indicate 17 September 1932 (or 1958) and 9 D F would indicate 9 June 1931 (or 1957), as D and F do not appear in the old Kynoch code words, and .30-06 was not listed before 1925.

I hope this makes sense and is of use.

Forgot to say, Imperial Chemical Industries Ltd existed 1926-1962.

many thanks, it does make sense after reading it a couple of times but I wonder how many of the Kynoch staff could understand it! Thats excellent, I should be able to work them all out now.

many thanks, Dave
