3.6 inch US Army M1890 Mortar
Just as rare as the Maxim gun is this 3.6 inch Mortar made at Watervliet Arsenal in 1899. It has a 3.6 inch caliber bore and is commonly known as a "bag gun". I have located 24 of the 76 mortars that were made and of these there are only 10 in private hands. This gun received a new rifled liner in 2013 by Matt Switlik. I am looking to buy additional M1890 or M1895 mortars and accessories.
