Thanks for the Wiki reference, having looked around there appear to be a selection of ‘Clerget 9’ engines on the web.

I agree that the Lincolnshire one looks the same as the one in the photograph but there should be a letter after the 9? Any idea where it was made and how it has been identified as a Clerget? Any thoughts when it was made? Why does it only have one magneto, is it an early engine? The inlet manifolds look more Bentley than Clerget?

More questions!!
