your brng 22 is a "trombone" model made between 1922 & 1974. Not 2 B confused with the later "squareback" model that followed several years later. it has a value range of $275 (poor) --$900 NIB which is WAY off. the trombones R highly collectible among Brng people. I have a trombone in 95+% with a Brng 4x scope mounted. wood not take less than $800 IF I was gonna sell it. never seena NIB which I think wood bring upwards of 2K in todays market. cant tell from yur pic if it has the (wheel site) or just plain open. the wheel site adds $$$
chek bore and operation if all is well and U like it BUY IT.
they T neet lil popguns. great 4 tree rats etc.
