Air rifles and air pistols from Suhl and Zella-Mehlis after 1945 2nd edition
Author: Ernst G. Dieter
After publication of the title "air rifles and air pistols after 1945 from Suhl" about ten years ago and after the discovery of new sources, the time seems ripe,
a revised, new technical details containing and also new models (at times unknown prototypes, patterns) descriptive edition.
In addition to additions in the form of their own, at least knowledge-related "new acquisition", there was both thanks to friendly people interested in topics
the possibility of models offered on relevant "markets" / forums, usually not available for public sale in former times,
e.g. the repeating air rifles from the August-Bebel-Werk, Zella-Mehlis, as well as other interesting developments (eg compressed air or CO² guns)
u. a. of the Suhl companies ETW and FAJAS.
