30" number 5 full oct bbl. Outstanding bore. Original pistol grip checkered Walnut stock retains virtually all the high gloss lacquer finish with a Swiss style buttplate. Gun is in extraordinary condition with virtually all blue and all bright vivid case colors remaining. No signs of having been used. Single set trigger. No rear sight seat. Midrange. After close examination, I find this gun 100% correct throughout. I have a Factory Letter that lists this as a 32-40 with a number 4 bbl. I think this might be a factory error. The gun came from a well known highly regarded collection. Excellent gun that would be hard to improve upon.
