Thankyou Air Ministry for the link, after many hours searchingthe internet I was aware of that site but it seems to be the only one that I know of.

Just a tip to those seeking reference drawings for cockpit interiors (especially ex RAF service aircarft), I always use the Research dept at RAF Hendon. You can drop your request via e-mail (see the RAF Museum web site). The reply normally comes through your front door some weeks later. Lots of photocopies of pictures/drawings or diagrams for any parts or layouts you are looking for/requested. They will normally invoice you for the photocopying but this is normally a nominal couple of pounds. Excellent service and recommended.

Any other web sites out there for control wheels?
