Frazer Nash FN.20 wiring help

Hi
Does anyone happen to have or know where I can find a wiring diagram for the FN.20 or FN.120? Any information or links would be helpful.
Thanks

Hi

AP1659A is the official document for the FN turrets – different dated issues probably covering the various turrets as they turned up. I have just one of the issues that you are welcome to a copy of – PM me.

You can get a copy from the RAFM but probably quicker to go there!

Meanwhile, for the FN20A Wellington see attached. I don’t seem to have the exact pages for the other aircraft for some reason but I suspect that there are a good few forumites who will have better info than mine.
