Yes it is a super book. The English version is actually more extensive than even the last German edition. Although coverage of vintage air pistols is light, the coverage of post-war gas, PCP, SSP and spring air pistols is exhaustive, and he covers just about everything, including the design technology, performance and ammunition. It seems that lack of interest from publishers is international, as his German publisher will also not fund his English edition.

I have tried to persuade him to self-publish, but he is over 90 now and sees it as too much hassle. I would offer to take over the burden myself but I have enough problems with my own book, and I am also pushing 80.
