The Winnenden is an earlier model than what Saxcop has, which looks like the Regent or equivalent thereof, which would be from the 60's I think. The Winnies are earlier...40's I believe.
Both are really GOOD vintage horns.
Kohlerts used to fetch good $ back around 2008 or so....$1000 Tenor, $750 alto.
But their market values have plummeted since then, to the degree where I cannot really buy one, refurb it, and resell without it either taking a loss or sitting FS for 6 months. That is the SOLE reason I didn't grab this one, as I said I saw it a few days before you bought it...so it had been up there and viewed a bit.
Too bad, because quite honestly, they are every bit as good as a nice vintage JK, Conn, Martin, etc...
BMB you got a steal there....
