Thanks for the help so far gents. Frank, nice looking model you have there!
I recall the hull being a bit more green/cream than grey, managed to find a similar colour from Tamiya deck tan, although a test patch is still a little dark I think, and would be a damn expensive way to buy paint!
I half am and half not looking forward to all those cranes. The plans are quite general so think it will be a test piece then knock out another 6. Will probably have to redo the funnel too, wrapped some styrene sheet around a frame, but got a little twisted, might have to be the block of balsa method!
