Well, I am the new owner of a Lapan's Foundry 2 1/8 bore cannon. It has a 0.25 Seamless steel sleeve liner. Previous owner use to lob juice cans of concrete at random targets. Sounded like fun. Bore looks pretty good. Maker was Lapan's Foundry is in Glens Falls, NY. Cannon marks have an (LP) on one trunion and (no. 98) on the other. I left a msg with them regarding any history of the cannon. Wood is ok, no rot..but probably will update it. Wheels are alum. including the spokes etc. Weight, no idea, took me and another guy to lift into a pickup and a third to balance the tail. Prob under 200lbs or so all told. Previous owner used FFFg, and gave me some loads that were already bagged (and 3lbs in cans.) I well weigh them just for interest but probably go more coarse and use the triple F in a pistol or somethin. They look a lot heavier than the 1 0z or so that I planned to use. Pics included, I cleaned up the nose a bit to see the liner, will repaint along with rest of cannon. I am brand new to this "sport."
