Anti-gas clothing training slides set

An extremely rare original set of 55x original pre-war Wehrmacht training slides on how to use Gasbekleidung anti-gas clothing equipment.  Some wonderful images are included, depicting the equipment of the period - comprising items such as the Mauser K98k, M35 Heer helmets and uniforms etc.  Whilst complete as a set, some slides are devoid of any visisble image due to some deterioration over time. Nonetheless, still a remarkable surviving set that would make for an excellent, unique addition to any collection of anti-gas related equipment, gasmasks etc and the like!
