Clearing out my garage today found a old box of holland & holland cartrdges, wonder if any one could shed some light on when they were made. There just short of 2 1/2 long, paper cased, got high velocity on them, steel lined, water resisting, loaded by holland and holland ltd, 98 new bond street, london W1. Also looks like cardboard holding the shot in, and Eley/Nobel on the brass head, Box looks very old and falling to peices.
