The 1904 grade F16 is essentially, after wartime and post war inflation, the same gun as the F25 shown here in this late 1930’s catalogue.

My F16 which weighs in at 6lb 7oz with 30 inch barrels.

It appears to have gone overseas as just behind the tang it is stamped ?B1574 which I am told is possibly a Kenyan registration mark.
