Hi Henk, The top right hand cush drive sleeve looks like a Swinging Arm A7/A10 one or a S.Arm B31/33 one.(two lobe shock absorber)..If it's loose on an M20 mainshaft it's the twin one. The one on the left I don't recognise as post war...Will need some dimensions for the layshaft...Ian ..If the S.Arm one is for the single mail me a price would you?...Thanks
I was thinking that....or possibly a B29/30..thier gearboxes are not identical to the post war B31 type. I have one of these in pieces if you want to check that possibility....Ian
