Recently, while thinking about buying a British made Diana 25, I was thinking about the markings. I know some of the early guns were like a cross over from the German made ones. Ive got one (with no visible date stamp on the stock) that has "British made" on the cylinder, rather than "Made in Great Britain". Id assumed this was to do with the festival of Britain in 1951. However someone recently told me they had a gun from 1954 that was stamped "British made".
I am quite interested when the change over was made to " Made in Great Britain".
If anyone can post up dates or their rifles and the cylinder stamping, we might be able to narrow it down to a few months.
Thanks
