I spotted this for sale on eBay, in a modelling category. Does anyone know what it is?
I can't get the images to display from my Imgur account. Hopefully you can access them.
It's marked with the name Auto Union and the 4-ring logo. It's apparent provenance is that it was taken from a German signals vehicle towards the end of WW2. The seller thinks it's comms-related: a soldering device, perhaps. But it could be part of the vehicle equipment. It has a removable reservoir for liquid, which the seller assumes to be fuel. I wondered if it might be a heater.
Could it be an aid for starting in cold weather?
