Now thats what a pre war is supposed to look like! Very nice and glad you use it!
At least in my limited contacts with O.Polices assembled during World War Two(42-45) many seem in nearly mint condition,as they were probably bought by the DSC for issue to defense plants/contractors. Those that have the firms "rollmarks" usually show "carry wear". Some of the non marked ones,my guess,were "perks" to the executives in these facilities. A Heavy Barrel 6" O.P. and a mint non Govt. marked S&W Victory,both came from the estates of wartime defense facility executives. /forums/images/graemlins/smile.gif
I like it, too. Looks like you have a "flaming bomb" ordnance mark stamped on the frame which means it was military issue - the historical value just went up! Try to get ahold of the Pate book to see if your serial is listed.
Anyway, nice find; and if push comes to shove, you are well defended.
