I remember Denis Curtis talking about that Piper head. Actually I think (Brian) Tintop spoke to Denis about this and mentioned in an older Piper thread??

The one Dennis knew if belonged to Jim Brokenshea.. I think is how you spell his name.

Frank, I think there was one somewhere close to you if I remember correct, maybe in Vancouver.
TG, yes, this one has EFI.
Here's another pic I found.

 Did the Curtis name ring any bells from say the sixties I think he was from England.
 How about the name Mick King, from same era ?

The EFI one was in the first picture Simon, the second pic does look Amal like though.

Here are a couple of links to the Curtis CB750/Piper.  Also some on the Vincent that Jay Leno now has.  He also did the frame for a Land Speed CB750 engined bike in 1975.

 That is also a Curtis front wheel. Not many of them.
 I think that bike ran 150 ish.
 And this year Dennis (Oldscrambler) ran 147 on a 760 cc 754..
