Original glass body, inner tube, and Bakelite caps of a Blendkörper 2H intended to be thrown against tanks or pill boxes to blind the crews in white smoke. This is a decent example with the important bits. There would have been some rubber gaskets which are not present. The glass is a little cloudy and the Bakelite is a little bit rough in appearance, both a result of being ground dug. The inner test tube does have a small chip hole in the bottom of it. The body and Bakelite are fine.
A nice example of a very interesting bit of WWII kit.
