Here's some notes on the dimensional changes between the 3 most common Nobler variants. The trend clearly went toward a thicker wing, and has continued in that direction. If you want to power it with a stunt Fox, the Brodak kit of the 1952 Nobler is probably the choice. If the power is more modern, with more punch, then the Greenbox should be your option. But either will give very satisfactory results. Most of the performance is in the trim anyway.
