Stig Comstedt, Sweden - Tube collection

Below you find a part of the tube collection Stig Comstedt. I am not a bona fide collector though I posses a small collection of mostly miniature tubes, saved for renewal purposes (for sets belonging to friends, colleges and anybody in need) meaning the tubes here are for sale or swap. I am at present writing a book on the history of the vacuum tube (in Swedish) and through my modest collection of, mostly out of print, books on tube technology might be of some help to RM members. My language is marked as English but you might write me in German (and in Swedish of course!).
