Hi
Am looking for some help please in identifying this. I have been told that it may be from a 20mm weapon, but no idea what.... could be off a tractor for all I know :-)
The mechanism still functions after a fashion. Turning the crank handle rotates and pushes forward the shaft, which in turn rotates the cog....
anyone recognise it? The only marking is 623 stamped on the base
many thanks in advance
Matt
