Thanks, both of you! I've looked at G. Harry's model in the Museum of Flight more than once and have some pictures I've taken of it....but couldn't tease out the right number from that or from the pics you posted, though I'd just about convinced myself it was five of each.

And thanks for the how-to, John. Very nice. Now all I need to do is stop by the hobby shop for the styrene sheet. I have a little Fourmost cutter - not as nice as the NWS Chopper, but it'll do the job.

added: It occurs to me that if 0.030 sheet would work, so would 1/32 bass wood. I probably have some of that to hand.....
