Thanks for the info and welcome, banquo. Yes, that's seems to be what I have, apart from the rear suspension - mine are chromed open coil springs. The seller had also fitted indicators, which I've kept, but made narrower stalks to keep it neater. The rev counter didn't work, so that's gone for repair. A cause for concern is the new chain - it's rubbing against a boss on the crank case near the front sprocket. The seller is looking into that re an alternative chain.
