You might also want to post your query on the Forum of The Mosquito Page (
The de Havilland Mosquito Page) which is the best source of information I know on Mosquitos and Mosquito operations - the amount of information available from members is stunning. You have to register on The Mosquito Page to be able to post on the Forum but if you don't want to do that, PM me and I'll place the query for you.
