So the carbine is home and apart these are the pics I have so far. It's in excellent condition with an outstanding bore. As a shooter which is what I wanted for a first carbine it should be excellent.
The first two shots are the location and a close up of the import mark. No way that was filed off ! Next it seems to be an Underwood round bolt? Underneath very clean and nice appearance and oddly colored. Barrel band doesn't seem to be cut down but I don't know. Muzzle crown is nice with no cleanup on it. Op rod and it's markings. Sights and their markings. Overall a nice condition gun. A couple of bore and chamber shots. I'll post more later.
