Reading up on Roundway Down, the royalists had a couple galloper guns with them. So I had a look see what bits I had to make one. I had a couple of plastic wheels the right size and a spare 18c ships gun. I cut the wheels and base off the gun and put it on a cardboard base, then added the wheelset. Completed gun below (with fig for size comparison) ..
I needed a draught horse and rider, so I cast them from one of my 18c moulds. The draught horse needed a little bit of work, the rider a new head and the coat detail altered. I had a spare horse and rider as well to use as the galloper guns escort.
