Hi Sven. Thanks very much for the close-up pictures., they are a great help. I can now try and fabricate the missing parts.
I bought it hoping that I could make something usable to fit my 1935 Comet 250 that I am building.
I have some pictures showing the same type of throttle fitted to a Comet, but thought it was an aftermarket one.
Thanks again for your help, this forum is the best.
Best regards, Colin.
