I saw your advert on Harry's old engine re. the Tangye and guess it may be one of the early engines I traded with Steve Green a few years ago - Serial No. 1753B ? I signed up on the Smokstak forum last year but can't get back into it presently hence this message. I would be very interested to see more photos of the Tangye and wonder if you might have acquired other English engines I used to own eg 20hp Hornsby, K & L type Crossley gas engines ?
