Hello, tonight is the first time I’ve looked at the Cannon forum. I saw a post by Eutycus on his toy firecracker cannon and I thought of mine. I believe it to be a CVA cannon. I’m guessing it to be about 40 years old as I’ve had it 35 years. It is 45 caliber and rifled about seven inches long. It was given to me by a friend who said he had not used it for years. All the metal was solid rust and the wood unfinished. I used a wire brush to remove the rust on the exterior and brass brush on the interior. I cold blued the barrel and finished the wood. I used 20 grains of 3F with paper wadding. I never fired a round ball out it. When I fired it the cannon would flip backwards about five feet. I fired it that way for years. I didn’t know there was to supposed to be an elevation wedge on the back of the cannon, lol. I made an elevation support out of popsicle sticks. Not HC but practical.
