My name is Ing. Petr Hemerle and I live in Prague (Czech republic).
For twenty years I have been collecting gas masks, breathing apparatuses,
protective suits and other things connected with protection of individuals.
My collection, which is my hobby, is fairly good. I try to document the development
of protective equipment since 1914 until now by searching through a lot of archive
materials.
My collection cover a period of time from 1914 till now. The majority of items
come from Czechoslovakia, Germany , Great Britain and Russia, but I have some things from Western Europe and USA too.
