Hi Sam, I have a brand new driving gear that fits to the output shaft. S and V supplied it four weeks ago, misunderstanding my requirement for the driven one. I was waiting for the dust to settle after their move to return it. Yours if you want it at cost. M in Newbury Dave
Sadly Dave tells me it now seems unlikely that he has a driven pinion after all. So I am still hoping something will turn up. I am hoping to find a good used example.
