bought it.
Just gloating.
the average selling price for it seems to be about $30 shipped.
I hope its in good enough shape that I can harvest the dampers/sliders. It was the right part number (m3501). I just want to try them out and at this price I couldnt resist.
I'm also getting more interested in itln style experiment with alps, maybe I'll remove the leaf altogether but use the dampers.
