right,today i got to talk to the man himself,Rex Pile!!!, he has looked at my frame and it isnt 1 of his ramyams,he did a total of 22 conversions on the mick whitlock whitehawk frames,converting those to monoshock,hence the name Rex Auto Monos =Ramyam, he is of the opinion this is indeed a sammy miller frame,but i have a pic of an identicle bike to mine but with a sammy miller 1 piece tank and seat unit on,that Mick Andrews has verified as being a Ramyam 175 twinshock? I am lost!!!!surely Rex is the man who knows his own work,he sent me a couple of press pages with pics of his bikes,and they look nothing like mine in the footpeg hanger plates,they indeed still look like a whitehawk frame in that area,which they are originally,buggered if i know!!!!
