Peter Hall was the pattern maker for WEM. His Atlantic Models offers HMS Montgomery, a Town-class conversion of a Wickes. 350 scale
Iron Shipwright makes a Ward with parts for several others in similar classes. 350 scale resin & brass
in 700 scale, Classic Warships made several, including a Campbeltown and an APD. Now OOP.
NIKO as mentioned Resin kit
