I am off to the Nationals in the morning so I won’t be around to watch the bidding end on this compressor but I would recommend you watch for it if you are in the market for a silent compressor.
From the picture and the data the seller gave me I believe it is a Werther 3/4 hp model and apparently it only has 4 hours on it.
He told me in an email that shipping was $40 for it so take that into consideration.

This compressor is worth at least $300 if it is a Werther.
Werther builds the compressors for the Badger silent models as well as the Silentaire compressors so they are good.
Good luck.
