Hey nothing wrong with trying to contact those involved. I was a little shocked to find out that the NCR guys are still around. Brook says he regularly has chats, and stays at one guys house when he goes to Italy.
I ring around all over the place try to work out do I replicate, replace, rebuild. No shame there.
I had a pantah powered race bike, fairly famous. Everything taken to extreme. (No paint on frame).
A guy I know brought it and said I want it back on the track. I do my research. Frame is made from a crop duster that ploughed in around 1978/9. Right so it’s either 0.7 or 0.9 chrome moly probably Reynolds. It’s been painted, but spotty rust marks. Rh foot peg mount is bent as well. Magnesium wheels.
I measured the rust pitting. 0.2mm, game over. Didn’t even get onto the engine, all ready got worded up about the con rods and crank from a previous owner who tried on the track 20 years ago.
So it’s, sorry mate, museum piece only. You could replicate a new frame, do a big engine rebuild, but then it wouldn’t be this legendary bike would it!
