Many want to learn, others do not. Went to LGS/FFl holder to pick up 5 Ruger .22 autos. Paper work was given to a young man with instructions to “Log in those Mark Is”. The pistols were a RED Eagle RST (No RST6 nor Mark 1 T-678 as they had not been invented at the time of manufacture of this 03XX gun). He put Mark I in log book. Next was # 0220X RST logged as Mark 1. Next was a Red Eagle Mark 1 T-678 logged as Mark I. The RST6 was logged as Mark 1. Last was a T-514 (target sites but short barrel) correctly as Mark 1. Some time during his writing I asked if he knew all these guns were not Mark Is and would he like me help show him differences. Replay was “No they are all look like Mark 1s.” I said nothing.
