My wife gave me a CVA 1/4 scale 70 cal Napoleon kit, 12" diameter spoked wheels about 30 years ago, and I think she payed about $300. for it. And I think they may still sell them, but there smaller.
I originally stained the wood, but several years ago, I painted it the green/gray it was in real life, she didn't like the color, but its in my gun room now, so who cares what she likes.
I haven't shot it in years, there's no good place to shoot it around hear, our club range wont allow any cannons.
I would post a picture, but I dont know how, Im a CIOF (Computer Illiterate Old Fart) But I can e-mail it, if someone cares, and want to post it for me.
Mike.
