I've got to hide that Riker in a custom made frame one day. But, it's a start. Coshocton Ohio Lance and scraper plus two Flintridge scrapers w/documentation in the back of the frame. Thanks Mr. Banonymous!
Little lamellar blade that snapped in (heavy) use. Unusual (and, although the FR material & form suggest Hopewell, edge re-touching suggests it's not).
