Well, we know that there were no Federal restrictions in 1917, and I don't know what the Texas law was that owulkd have been a problem and since I am not a lawyer anymore, I don't think I want to do the legal historical research that would identify it. Pawn shops have operated under some peculiar restrictions over the years, though, designed to (in theory - in practiceit didn't do much in that regard) keep them from taking undue advantage of the customers.
In any case, in these days in Texas - if the gun was sold to the pawn shop, or not redeemed so that it was forfeited to the shop, they can and will sell to anybody who can pass the instant check or has his CCW (or, for a gun that qualifies, to anmybody who provides a valid C&R tag). Last handgun i bought, in fact, was from a pawn shop. In Texas, where i live.
