Thanks Gary. I have been watching that (and it is nearby) but it is the civvy version and the naval armaments in the right scale look difficult to come by. I missed a naval version in May and will just have to be patient!
My dad served in these in WWII and I would like to find a model of one if anyone is ready to part with theirs. It would be for display purposes only, so unimportant if a non-runner or in need of repair/refurbishment.
