Having built a few mortars my daughter knows what I can do. She saw this at a pawn shop and took the picture. She said they paid $5,000 for it and were asking $8,000. First thing I saw was the size of the axles on the wheels and knew it had never been shot with any heavy loads. The last one I had would put a 16 pound bowling ball out of sight with 3 ounces of powder. Recoil is very high when doing something like that. The one pictured would never hold up under that type of load.
