Hello!
I am completing a 1/4 scale ponton bridge, a model 1863 Cumberland folding Canvas ponton bridge. Might you have a field gun in this scale for display use with this bridge? We do school and historical group demonstrations.
WE also build a 1/1 scale bridge of this same model.
Thank you for your interest, but I do not currently have anything that would fit your needs. I would suggest looking at e-bay to see if anything might be available, although most cannons in that size would be working models, which are are expensive, but there are also some Spanish decorative models from the 1970s that can be had pretty cheap. Just depends on how picky you might be about the time period and type of cannon. Sounds like you may be looking for a specifically Civil War model, but there are few to none of those among the Spanish replicas.
