12 gauge with 3 inch chambers and automatic ejectors. Has been threaded for choke tubes and sling swivel studs were added. Nice dark wood with figure. Good case color. Blue is thin in spots about what you would expect of a 85 year old gun. 1 5/8 x 2 5/8 14 1/2 lop to front trigger. Has been used as a turkey gun with great success. Good tight gun.
