Hi - I am sorry to bother you with this, but it is kind of driving me mad trying to figure out what it is. I found this at a antique market in Warszawa last week, and I guess it is from the 30-40s. I worked as an military officer for a few years with mine and bomb disposal, and I kind of get the feel that it might be a timer device for a bomb or torpedo? But I guess it also might just be for industrial use. Has any one here seen such an item before? In the metal can/cartridge, it is set upon thre sliders/bolts, so you just lift it out. I get the feeling it comes in a can, you just pul it out and mount it in the same way in the device, what ever it might be?
Best regards.
