Did it have a parkerized finish and a lanyard ring? That’s pretty much the determining factor. The one’s to look out for are the ones sent to the Brits chambered in .38/200 (.38 S&W with a 200 gr bullet). A lot of those were rechambered to .38 Special after the war, but the bore diameter is .361 so accuracy is marginal. British proof marks on the barrel just ahead of the frame are the tip off.
I dislike admitting it, but ... I am not certain about the lanyard ring. I think it may have been parkerized, because I definitely recall that it did not have the usual high polish smith finish.
I remember briefly thinking “this might be a victory model”.
