Hello Joolz, I appreciate the picture of the limber box. It looks like a natural to accompany a medieval mortar crew. Could you please post dimensions and is it built fom dimension lumber and stock hardware? Thank you for your sharing. George B. :thumbsup: Also, if I may ask,why do the authorities dislike aluminum wrapped charges? We used a thin plastic bag wrapped with aluminum foil in 6 lbr to 18 lbr cannon with no problem except having to worm scrap out each shot.
