This is my WWl 1911 not as original condition as the O.P.s 1911 found it in a Pawn shop in 1965 paid $42 dollars for it, the finish was badly worn so had it reblued.
Both the O.P.s and mine came from the same Mfg.group of 69,613 Mfg.ed for the US army by Colt, my S/N 26598 was Mfg.ed 4,825 later then the S/N 26,0373 of the O.P.s.
In my reserch an item that can't be proved today is both these 1911s came for the same group as Sgt. Yorks 1911 he used to Kill the Germans during WWl and he received the Medal of Honor for.
This came from an article Mrs. York told that her husbands bring home 1911 had been stolen but said he had written it's S/N as 25,4648.
I have seen other article with different S/Ns and can't say the article where Mrs. York is really correct if any forum member know something please let us all know.
Anyway the O.P.s find is a really great WWl 1911 glad he got it.
