Tom, They must be coming out of the woodwork. I picked one up in Souther IL two weeks ago. Don't know anything about them, but mine does have a serial number plate near the seat rail which is how I identified it as a red devil. I'll get a picture of it and post it.

Bob

Steve,
Thanks as always for a thorough explanation. It makes sense now.

I am looking for education. I was under the impression that when you 9 ported the early Macs you put a "9 Port" piston in the engine. I thought the 9 port pistons had the window or cutout along the piston wall like the 91 and later pistons. The third port engines through the Mc9 had a full skirt. I ...
