This is a very good Marlin Model 81 in 40-60 caliber rifle with a 28” barrel and shotgun butt. It has an adjustable set trigger and Lyman rear tang sight. It retains 45% blue with very good mechanical function and a very good bright bore with strong rifling but does have some dark frosting. Most 40 caliber bores are not very nice. The wood is very good with only a couple of minor dings. The serial number is 7179 and is an early 2nd model, made in 1883.
