Nice looking long tangs, but not sure which "War" you are refering to as Browning/FN didn't produce the 20ga Superposed until '49, I believe? My own 12ga Superposed (28" barrel choked Full/IC ..great rooster combo!!) was acquired by my Great Unc at the PX in Japan in '55..along with his (mine now) Mdl 70's.

That 20ga looks damn near new! I had the chance to purchase a late 50's 20ga Pigeon, LNIB when I was in college (1990) for $1500. While I had the cash, and I shot a limit of roosters the day I tried the gun out (3/3), I declined the offer. Obviously the cash was more important to me, and the ability to kill 3 birds with a gun (that held 3 shells) if the opportunity presented itself. I probably blew the $1500 down a shotgun barrel anyway, so I wish I'd of bought the 20ga!

Should be a nice day for chasin' pen birds, stop and shoot doves too.
