One of my gun shop Pals showed me this today. It's a dot 1944 with everything looking as it should...except the barrel. As you can see, it is shorter than any I have ever seen. The fit, finish and crown do not exhibit any "Bubba" traits and are identical to other Mausers I have. Same factory look. There is no bayonet lug, nor provision for a cleaning rod.
