Hi guys, I've had this in my collection for a while but still haven't been able to identify what it came off. Every visit to a museum involves scouring every Pak/Flak gun, generator, motorcycle etc. but still no luck. I'm leaning towards German based on the colour and the quality of the engineering although it lacks the plethora of stamps usually associated with German equipment. The cylindrical handle spins independently of the rest of the shaft and the folding mechanism still works perfectly. I've also been trying to figure out why it folds, is it removable and needs to be packed? Does it come from a compact, portable machine? Is it just over engineered? Any thoughts would be most welcome, thank you for your time.
