I am a bit confused about the markings on Collins bags and their meanings. I think this bag is 70s, post Enid Collins, but here are the clues: No "Enid" or "ec" anywhere on the bag; the Collins with a horse logo is on the outside; and the stamp shown is in the inside.
Any Collins bag experts around? (please and thank you!)
