This is a Konig driver's seat, but sure looks a lot like a Scheel 401/501, except for the leg bolsters (these are a bit higher at the end of the cushion).
Good condition overall, with the obvious fabric tear and small foam damage on the upper outer bolster, an the small tear in the back. Has sliders bolted to bottom, and I have the male mates to those, as well as a beefy mounting bracket I don't know what to. The sliders aren't included.
$300 plus $75 shipping in lower 48.
