Top Single 34" Vent Rib. This is the std. low rib NOT the Vandalia High Rib. All factory original NO aftermarket modifications. Factory marked IM (improved modified) with factory bore of .735 and .025 choke constriction. Barrel has #1 stamped on the bottom which I assume ment it was part of a combo at one time. Barrel show's little ware and I would rate it 94-96% condition easy. Has factory long cones, 10mm stright rib with twin beads, middle bead is silver and front is white. Thanks for looking.
Will be shipped insured through UPS ground.
