Thanks for your responses, Bill!
I've always been fascinated by the idea of scale model cannons since the movie "Beau Geste", where the one brother gets shot by a scale model cannon on a scale model ship...(I have it on DVD now)...
Perhaps when i fanally get some time to myself, I'll turn a brass barrel and make up a hardwood carriage...If I can find some plans, or good pics...
I live/work only a few miles from Fort Niagara; they have reenactments a couple times a year...I'll have to go there and see what they have in the way of naval cannons...(Fort Erie is only an hour's drive away, too)...
