This is a pre war Bavarian private purchase patent buckle. This buckle was used by placing the raw end of the belt (which would have been a special type purchased with the buckle) under the raised stamped out piece in the center. The belt would have had two slots so that the prongs would go through it and be bent over. These two features secured one end of the belt. The other end of the belt had no metal fitting. The way it was fastened was to press the raised button on the spring loaded catch and then slide the other end of the belt under this catch. The angled cut out over one end of the belt made sure the other end of the belt slid easily over it. When the belt was in the proper position, you just release the spring loaded catch and the serrations on the other side of the catch pressed into the leather and held it. The benefits to this type of buckle were that you had an infinite number of positions to latch it, not just one inch adjustments like on the issue belt. This enabled you to perfectly fit the belt to you and made sure you looked your best while on leave or walking out on the town. These would have mainly been used by One Year Volunteers and senior NCOs, but any soldier with the money could have purchased one. I have seen a couple of these illustrated in books, but this is the only one I ever had in hand. This one was most likely worn by an NCO since it shows extensive wear from combat use. OK, On to the buckle itself. Dan
