Hi Wink,
Incidentally, my grandfather was a very decent modelmaker. Amongst other subjects he carved a 24th scale Sptifire Mk. V from wood. This was in the 1940s, way before plastic kits and decals were available. No PE or resin either! All he had to go on was a small 3-view plan of a Spitfire and possibly a few poor quality b&w photos. No plans. Despite this, his Spitfire looked better than the 24th scale Airfix kit I build as a kid.
Another point of interest is that the control surfaces on his wooden Spitfire all moved. If you insert a screwdriver onto the rudder pedals in the cockpit the rudder moves. Similarly, by moving the control stick the ailerons and elevators move. This was achieved via wires inside the wooden model.
I'd love to have seen what he could have done with modern U-boat kits, and resin and PE aftermarket stuff.
Cheers,
Dougie
