Think I read somewhere that ex military RR engines may be used to power such recreations...? I also suspect that the ability for the finished machine not to be required to display reflective numberplates may well determine the age of the identity to be adopted from whatever donor might be found.... I had the opportunity to get close to what I imagine may have been a Petersen Bentley at a car show held on the marquis of Bute`s estate on the island of Bute .... Just great to see the craftsmanship involved in recreating such a wonderful machine, though I did hear comment that it was not real, which was perhaps expected as there were some "real" vintage Bentley's in attendance..
Real or not, I thought it a marvellous machine..
