PW Folding Field Phone Back Pack Wire Layer

I believe this is a Polish post war folding backpack field phone wire layer. It is very similar to the German folding layer. It includes a hand break for providing tension to the wire when laying it and there is a handle to allow you to reroll it. This is a piece that I used for reenacting for a while but, since I have a few others, I just need to move this one along to make some more space on the shelves.
