Sometimes I go on eBay and buy used Tootsietoy artillery. I look for the worst ones I can find so I can get them at the cheapest prices. Then I strip the paint, repair any damage, primer it, paint it and add new wheels. In this case the back end and the barrel were broken off.
I added a new barrel from a Roco 8 inch artillery piece, usually these guns are 155mm.
That gives me a battery of 155mm and a single 203mm howitzer.
Which one is the original?
A battery of 155mm and an 8 inch together.
