I’ve recently inherited a set of Redwing castings but unfortunately no drawings, Just wondering if anyone has an old set they no longer need? PM research will sell a set of drawings but at over £100 with postage from America this is a bit much for me at the moment. There is an excellent build series on the net which has photos of most of the components overlaid on the drawings so I can get almost all of the dimensions from there, there are a few minor dims missing but these aren’t important and I can do a ‘best fit’ with the castings. I can’t however work out the valve spacing in the cylinder head, the drawing reproduction is a bit fuzzy in that area. Many Thanks.
