Excellent ...thank you for all your hard work.

Have you ever considered compiling and publishing your complete series as a book / booklet? I do not know much about the publishing industry but suspect that you have already done most of what is needed to 'page set' your series. Or could difficulties arise with pictures and ownership of pictures from magazines?
Even include copies of the manuals as appendices. Maybe Air Arms might sponsor it?

I should add that my fear with electronic publications is that in time the links can become inoperative for various reasons and so access to the information becomes a problem or impossible.

Cheers, Phil
