OK Steve, ... Glad this could be of a help to you, sir. Their 1:48 SO radar mast arrived the other day. It is very good. The guy used the actual blue-prints of the mast and dome which Don Shannon at Battleship Cove supplied. So, since the guy just rescaled it to 1:72, it should be just as good, right?
I can't wait to see it on my 1:48 Merit early-80 foot Elco PT kit ... I'm going to have Stan build it as the 190 "Jack'O'Diamonds" later in the war. I just wish someone on Shapeways would create correct Mark XIII torpedoes in roll-off racks and D/Cs in roll-off racks in 1:48 and 1:72.
