This is an Ithaca Model 37 Vent Rib barrel. 12Ga., 2-3/4 Chamber, 28", Fixed Mod Choke. The Blue is 98% with some very light fading behind the lug and a small mark on the edge of the muzzle. In the pictures you can see that it looks like the front part of the Ray-Bar front bead is missing. When you look down the rib you can't tell, and the bead is bright but I want to point that out. This is an interchangeable barrel and can be installed on any 12 ga. with a serial number over 855,000. $250.00 plus shipping.
