Did you not ask this same question last year at this time?

I did ask a question on Storm boats last year (and I'm grateful for the pictures and info that was provided), but then I didn't know that there were two types of Stormboats, British and American.
Now, I'm talking Storm Boats here, not Assault boats, which were quite different. At Arnhem the British used British made Assault boats and the Canadians used British made Storm Boats.
I know that this question is a long shot, but I'm hoping that someone somewhere knows the origins of these boats. Even the RE museum in the UK doesn't have an idea.
