I believe these 3 vials to be German WWII gas detection reagent vials . These were found in Russia in the same ex-battle
field that unearthed the German horse gasmask also shown on this web site .
The vials seem to be made from a brittle clear plastic material . Inside these tubes are 2 round glass
balls with some unknown chemical in them . These glass balls are seperated by a plastic plate and a white substance
that may be cotton (?) and then a light brown granule . On the outside of this vial is a black painted rind and a large "E"
embossed into the clear plastic . The exact maker is unknown to me . I was told that when used this would detect a certain
type of poison gas . As far as I know this vial would be inserted into a test device and some how when the 2 glass vials were
broken the 2 chemicals would mix with the gas and turn the brown material a different color indicating a certain type of gas
. If the reader has more information on these vials please e-mail me !
