Yes that a younger Tiger and me
that one was built same way as your frame and wrap, but while I was out of UK it was stored under a leaking roof, and water got between wood and fibreglass, so rebuild required, that's when I changed to fibreglass hull.
As for props, Sitek says they are 3 blade which is what he will supply, but he supplied my 5 bladed. They works so leaving well alone. The Tiger class had 4 four bladed props, according to one of her divers, who had to dive to check them out.. My Jecobin plans of which there are two versions, firstly show, 3 bladed but the later defo 4, this is what make the hobby fun (I think)
Image of her on the ground is wood hull remainder test tank of fibre glass
If you need any shots of the real ships, let me know BTW just seen shapeways do cracking turrets BUT really pricey
