June Hardware: 1920s National/Oscar Schmidt Post Tailpiece

This same type of 20s tailpiece can be found on Oscar Schmidt tailpiece-loaded guitars as well as a very few Harmony products, too. I believe it's also found in a slightly different form on the earliest Nationals as well. Anyhow, if it'd be of use to you, give me a buzz. These are extra-rare units.

...and there's the "butt end."
