This loader is in perfect condition. Very hard to find these days. You will never found one on the internet. Very good quality, much butter then the ones in WW2. 
The additional feature it has—similar to the WWII version—is that it clears the belt, ensuring the cartridge seats properly. It is of heavier construction than the WWII version and operates much more smoothly. Dated 1913 and a lot of marks and a low serial number. This one is definitely a museum piece
