Once you get the rifle can you post pictures of the bolt serial number, rear pad, markings on barrel. Check barrel if 2 or 5 groove. Check butt stock for evidence of screw holes for cheek piece and if present, a measurement of the holes centre to centre. I'm very concerned about the serial number on the wrist....you can see horizon lines where the butt socket marking have been removed....no "LB" nor inspectors marking. The "71L" is engraved whereas the "0350" is stamped...never have seen this done on a Long Branch sniper.serial number always stamped. The scope marking on the butt is also a non standard...yours is marked "C-405" ...should be marked "405C" for a REL scope. Thread size on the pads would also confirm what you have. I'd get this checked out before a restoration....you don't want to put big dollars into something that's not genuine.
