Got this locally today and gave it a quick polish. There are still some spots that could be removed by sanding but I think I'll just tighten the pivot and see if she takes an edge before I get too carried away. It is a RUGRA, Rudolf Grah Solingen-Weyer. Two odd things about her are that she is stamped 4/8 but measures 11/16 going the modern way edge to top of spine and there is no Solingen or Germany stamped on her. Also feels like the blade is a bellied hollow. We'll see after dinner how she hones up.
