Hi Gordon ...
I believe both WK518 and WG486 remain as God intended ... No clue about the Navy (Chipmunk) ... Sorry.

All understood ... Just leg pulling

I wonder if you might be able to help if you've got original RAF Form 700 info. I'd like to try and post examples of the various 700 docs that made up the Blue Ring binder that accompanied each airframe ... For historical purposes. Smudge might also be able to help us as he has a wealth of experience as a RAF Ground Engineer where, amongst venerable service on the Herc, he also looked after AEF Chipmunks a few years ago.
If we can I'd like to capture an example from each of the Sections from the 700. I'll drop you a PM to follow up ...
