Here is an armed trawler from WW2, many of these were built in Beverley at the Cook, Welton and Gemmell shipyard, they were launched broadside. They built mainly trawlers, minesweepers and some Flower Class corvettes according to one website.
Their output seems to have been immense.
Although supposedly 1:300, it scales out to be about 150 feet in length in 1:350, so it will do.
This is from Warlord Games, their Cruel Sea range and was obtained for me by Mighty Lancer in Bridlington - thanks Nathan.
This is a resin kit (not may parts), you get a nicely moulded hull and then white metal fittings.
There are no instructions supplied with the kit.
The photos show the box and then its contents.
