Andrew: It would have be interesting to see the photos from Aeroplane Monthly. Any chance that you can scan and post/e-mail the pictures? I've checked my copy of Alfred Price's book, but I have the Second revised edition. In this edition the page 213 contains Appendix A and no picture of the 28 Sqn Spit. On page 212 I find two pictures of FR 18's, but they're both from other squadrons.
Here are the pictures from Wings of Fame, Volume 16, which I've mentioned in my first post:
I'm posting these scans under the standard "Fair Use"conditions, which I trust everyone here will respect. (See http://en.wikipedia.org/wiki/Fair_use)
