Good question, and on a purely informational level, should entice some interesting responses. I'd be interested, as BP C&M is a truely unique subject in this country today. I fear that the response may be muted, however, due to the results of the latest election, and folks wondering if our "hobby" will survive "Regulations & Rules" sure to follow. That said, I'm building a soda can mortar using Double D's plans in his K.I.S.S. Mortar, plus have developed an interest in handegonnes, got a tube ready for one, and a 1/2 scale Mt Howitzer looks good in my shop! Just working on the mount now, but I'm lacking in woodworking skills! BoomLover
