1937 s/42 questions

[trigger643]

I have an opportunity to purchase a 1937 s/42 in the t serial # range. Gun is the property of a veteran and comes with a notorized letter, but no capture papers. The veteran claims he has not reblued this gun and has had it since he took it from a german sgt in early 1945. I rate this gun blue @ 98%, straw 60%, comes with 1 police magazine which does not match, drop eagle "2" marking on holster, I can't read maker, and is matching, including grips, except for magazine. but here are my questions...

1. Would the bluing method used in 1937 be shinier than say, 1938 or 41? This appears to be an almost deep commercial type blue. There is no smudging of markings (except on the right side proof marks, I assume these were applied before the final polish?). Halo is evident on "1937", serial#s, "s/42" on toggle. Edges are crisp. There is thining on the grip straps, on muzzle, but little wear.

2. Would the toggle pins be fire blued? These are.

He's asking $1,100.00. I don't doubt this fellow's story. I'm just concerned about his memory.
