That's a Western Arms Long Range by Ithaca Gun Co. and per http://www.gunshop.com/dgsnos5.htm was made in 36' or 37'. It should have 2 3/4 chambers and with 26" brls might be IC/M. Western Arms was the lowest quality, below the Nitro Special, of Ithaca SxSs but it's certainly a solid utility grade gun. 20s are more valuable than 12s. Cabela's has a very nice 16 and you might compare the case colors on his 20g: http://www.cabelas.com/cabelas/en/conten...erarchyId=11657
