I just bought this at an estate sale tonight! It came with some pictures and other papers from Germany. I only paid $40 for the entire lot, so I am not out alot if this turns out not to be WWII era, but it sure looks like it to me! The only markings I could find, other than the guys name written on the inside flap, are the letters RBNr with the following numbers: 0/0561/0163. Is this WWII era? If not, what is your best guess of the time this was used? It looks identical to alot of the map cases I have seen on the net and forum. Any idea of value? I’m not looking to sell it, just want to know if I got a good deal! Thanks!

Bill
