I've made around ten guns to date - That one was the first "proper" gun. The barrel is a hydraulic pipe liner, cast into a massive aluminium jacket by gunmaker in Birmingham. I built all the rest from scratch, apart from the wheels, which were supplied by Croford, who make wheels for the big royal carriages our queen rides in on state occasions. Since this gun I've built another nine.... some field carriages, some naval and garrison type. I'm in the process of having a new all steel barrel made by an engineering company to my specs..... two inch calibre, length around four feet, with several reinforces back towards the breech end.It's all steel, and will be powder-coated in silver. This will have a naval carriage. I'll be casting lead balls for it.
Should be nice.
