Gap In The Market (aviation publishing)

Years ago, there was a really useful and inexpensive book called the Vintage Aircraft Directory, compiled by Gordon Riley. Vintage aircraft in the UK were listed by type, with info on owner/base/condition. The last of the series came out in about 1982, and as far as I am aware, there is nothing comparable around today, though Wrecks & Relics covers some of this ground, broadly concentrating on non-flyers.

The directory showed, for instance, that there were twenty DH 89a Rapides, and that 8 were airworthy. In 2005, where is such information easily available? G-info (CAA website) is quite useful, but every entry has to be examined individually.This is not too bad if you are looking at, say, Comper Swifts (3) but not so good for Tiger Moths (182).

Warbirds are quite widely documented, especially Spitfires, needless to say, but the slightly less glamourous types, ie most of them, seem banished to obscurity. So where are those Ansons, Stampes, Ju 52’s ( 6 in 1980), and all the rest.

It seems to me that there is a good opportunity to publish such a guide, and much of the information needed would be available on-line. The useful bit would be to boil it down, and present it in a quick, easy-to-read format.
Anybody want to take this on ?
