Very cool. Manufactured in 1969, and likely imported by the original Air Rifle Headquarters in West Virginia. Would love to see some more photos!

A few notes:

Definitely a leather piston seal originally.

Iffy on having breech shims. Those are nice to have, but hardly mandatory, make for smooth cocking and reduce wear to the finish on the sides of the breech block. But can be hard to get in there if not originally present. The HW shims are made in two diameters, you want the smaller one. May have to buy these from a dealer or importer.

The sight rails on HW's made before 1978 or so are spaced wider apart (nominally 13mm) than on newer guns (11mm) – be aware when buying scope mounts. Take good care of the match sight, the older ones are harder to find!
