I've seen this type of letter before, I'm pretty sure they wanted Lugers specifically for a reason. The same government was handing out rifles and ammunition to loggers on the West Coast. Different time, different attitudes - you could also ask for a permit to carry from the local police station - and get one, even in the city. The last Chief's Letter (permission to carry a pistol) I saw was dated 1970 - and the guy who showed it to me was a former member of the SS.
