I wonder if anyone has any pictures of the early version of the jack mounted on the Panzer I/A. Both mine and Laurent's pictures in the walk-around section have a later version of a track for public display purposes.
I'm curious as to the storage of the cranking arm, it seems to fold back on itself to be stowed under the body of the jack and then you need to bring it to the other side for clearance to crank the jack up. Any insights?

Don't know where they come from. Possibly eBay. HTH

Thanks,
