Interesting point Guy about the plasticine impression. I will try that but the impression is feint - hence me mis reading the AR for AK and the "1" digits as "4's". Also if I can get a clear reading of the engine number and the block casting date (which is very clear as Oct 2002 ) I'm hoping to avoid the dreaded Q plate. I do have a receipt for the engine from Autolusso - but nothing on the receipt to indicate provenance - although am still trying to get more detail from them.
