Ex 49'er, That sure is a nice looking cannon you have there! We like that fact that it is has a 1" bore, Tube. Probably will be a higher velocity field gun than the GB size guns. Those are great photos you have there, but it's a little hard to see if you have lead or zinc cast cannon balls. Which are they and could you post a photo of the mold you use? Thanks, and have fun shooting your new cannon!!
