Pieper Bayard

The barrel is integral with the receiver.  The tube that houses the recoil spring sits atop the barrel.  The Bayard utilizes the same spring steel extractor, with a little wedge welded onto the end, as the Model 1900 Browning.  The breech block is of a piece with the slide.  The slide represents a very complex piece of machining.  The upper portion that houses the spring and spring tube has been drilled out, and the rear of it has been plugged with a carefully machined piece of metal.
