Gene,
That is my son Steven's plane. And it is based off a PM. If you read this thread, there were 4 PM's. Anyway, Steven's PM is based off the second one Big Jim built (Which is the B&W picture at the beginning of this thread). The cores for that plane were actually cut by Big Jim and they belonged to Hank Forbes, which then ended up with Jose Modesto, who in turn gave them to Steven. On the wings themselves was a note from Big Jim! Recently I have been trying to understand all of his designs and he had quite bit of them.
thanks
Joe
