I know my car ( I believe) does not have its original engine and would expect that most do not. Part of the issue is that today, we are more concerned with originality. When Ulsters were new, they were comparatively inexpensive competition cars. If someone sent a rod out the bottom of the crankcase, they would have been less inclined to have it welded, and would have secured another, perhaps from an engine that had been damaged in another way. Unlike the regular Austin Sevens(saloons, tourers and the like),Ulsters, like any competition car, were somewhat expendable. It wasn't about originality, it was about staying competitive. And if it was raced much by successive owners, things would break, be improved, modified in an effort stay competitive. It would be a rare car that would retain much of its original bits.
