Back around 1976 I was at a state range outside Detroit shooting my first handgun.It was a ww2 Browning high power.The only other shooter on the range came over to talk looked at my high power and told me the year it was made and explained the German army marks on it.The man had several 4 inch smiths a model 29 a 19 I think a model 28 and one other I can not remember.He told me about having them all round butted to make them easier to carry . We talked for awhile and he inferred he was in law enforcement. I remember his hair was a little long and a big scruffy mustache.I didn’t ask where he worked but he had some fine tools to work with.
