Powerplant AP

Morning folks,
I’m in the middle of an ‘interesting big job’ somewhere in Cambridgeshire at present, and am looking for a bit of help.
Do any of you kind people have a copy of AP 2140 B,C,D,E etc Vol 1 Power Plants, Merlin, General and Technical Information. Looking for one for comparative purposes.

Cheers and thanks in advance,
Camlobe
