Hi Southwest (which part of the southwest???),
I believe the author works from home as per the site Dave gives above, also
www.flightstore.co.uk/ they also have very much reduced Pooleys Guides at times - well worth getting a copy - latest one I got has large diameter plastic rings - crap for the book shelf!, but lies flat and is very usable, I hope these help.
For information of anyone with an Icom IC-R7000, there's an original (an unused) Remote Handset and modular PCB IC-R12 availabke on eBay (#270492023346), I secured the previous one he had for sale (for far too much money, but it is a genuinely rare item), but as the 7000 is a bedside scanner, I daren't use the switches at night - they are so positive and superb quality, they produce a click which disturbs my better half - hence justifying the purchase with her blessing!!! Got one for the 545 for a lot less money.
