Collectors, I have a stash of old Kynoch red and yellow and the even older Kynoch cartridges and a few part full or empty boxes. Some of the cartridges are exposed in tattered boxes and corroded. Some Rigby-labeled boxes. Calibers include:
475 No.2
500/465
500/450
450/400
9.3x74R
350 Rigby magnum
350 Rigby No.2
350 Rigby No.2 sealed tin of 20 cartridges
35 Winchester
280 rimless
6.5 x 55

and many loose rounds in the above and in other calibers including what looks like a 50 cal with bullet diameter .510 and case length .390+
Also a number of .577/450 Martini Henry and a old Snider round or two.

If interested PM me.
Regards, Tim
