Here’s an interesting tropical tin of cartridges. There is no label on the tin, and I don’t know if it ever had one, but it is stamped W.J. JEFFERY & CO LTD and 577 S. I believe the ‘S’ refers to the solid 750 grain bullets. The tin contains a standard looking box of 5 Kynoch .577-3" Nitro Express cartridges. I’d appreciate it is someone can decipher the lot number 29 J D/S on the back of the box.
