Are you really in love with a BACH? Wow...that's a first for me. I guess as the old saying goes "To each his/her own!".
I mean I could see someone really wanting a Mt. Vernon or a vintage Bach but that horn looks like it has been through the mill and back.
I have a suggestion for you....check out
www.dillonmusic.com and check out their selection of Bach's. You might find something there that you like a little better! (if not then happy bidding!)
