Picked this Cragstan VINTAGE 1950s METAL CAP FIRED ARMY CANNON - JAPAN up at the meadowlands flea market last Saturday for $5.00.
This cannon is a little to wide for Prewar O gauge so I think I will use it on a standard gauge flat car.
Will make a wood type wheel cocks platform that mounts on the flat car to hold the cannon in place.
Then to make this more of a standard gauge toy like flat car, I will stack some small cap boxes and shells/bullets (that I have to make) on the flats card as a extra supplies for the cannon.
If I do not use the flat car idea, I always could make one on my tin Hallmark houses a American Legion Hall with a cannon out front.
The quarter is just for cannon dimensions.
I also saw the box for the cannon on eBay (did not buy just copied the pictures).
