1909 Imperial Unit Marking Reg's: This is a complete copy of the original Imperial German Unit Marking Regulations of 1909(in use during WW1). Most collectors can read the more common unit markings, a line infantry unit, perhaps even a Guard unit, but what about the ones that are harder to read? What about a field bakery unit? What about the ammo train of a corps heavy artillery unit? What is the difference between a block "R" and a script"R"? This will describe all of these markings and a lot more. It will increase the historical interest of your item as well as the monetary value - paying for itself many times over. Impossible to find an original copy!! Don't let this one get away. Please check out my other auctions as well. I combine shipping. Shipping to Canada $4.50.
