The pouch and Gasplane are dated 1940. The pouch is the rubberised type and the markings show it was manufactured by Paul Reipert, Hildesheim in June 1940. The Gasplane was manufactured by the Wolfgang company in July 1940.

The markings on the pouch and Gasplane are of the type you can expect to find on early examples with the manufacturers name being used rather than a three letter code.
