Went to the sale...not as good as the photos but a reasonable example, engine running of a fashion. Sold for £8500, but I don't think the buyer bought the original engine. There were a set of wings (front and rear plus bonnet, nose and boot, which I assumed came from a saloon, until the remnants of the folding roof appeared on closer inspection.
One buyer appeared to purchase all the engines and sundry parts. I have his phone number. PM me if interested.
