That's looking the biz, Geo.
And yes, it must be rather large in 1/48th scale. It's surprising how big, and how heavy, the real thing is, too. When I towed one of the RNHF examples with my SWB Land Rover back in the 1990s, the crew were slightly concerned in case I ripped off the tail wheel. I asked them how heavy it was, with the under-slung (inert) torpedo, and was told 9 Tons (might have been 7, I can't remember) !
I was more concerned that the weight would rip off the rear cross-member of the 'Rover !!
