Up for a sale is one vintage flashlight for you collectors out there.
Estate sale find and I think it's from the 1950's.  I researched this name on the internet and couldn't find anything so I'm pretty sure it's very rare.  Maybe European made?
On the tail end it says Carstens.  It's in very clean condition without any damage.
I thought it held two C cell batteries and when I tried them they wouldn't go in.  So I have no idea what size battery or batteries it used.  Also because of that it's un-tested.
It's kind of Art Deco cool!
