These backchecks do not have the last layer of leather like you described - "like thick elk hide". There is nothing to suggest that there ever was any leather on the checking surface. These hammers have been checking on the dense-ish felt surface. You stated that there was "usually" a leather layer for the checking surface - was it sometimes just the felt? > Sometimes the > whole thing was all leather and the softer stuff was usually Rabbit. I don't understand what you are referring to: "the softer stuff was usually rabbit". What softer stuff? Where was it? Thanks again! Terry Farrell > Other item is backchecks.
