Re: Buescher sax
There's not a lot of good news on that horn. The serial # puts the production date some time in 1923. The good news is that a low pitch horn is compatible with modern instruments in an ensemble. If it were a high pitch horn, the value would be zero. The True Tones are sweet sounding horns with a reputation for playing somewhat better than other horns from the same era, but hey don't have a high market value.
I suspect that that horn is neither an alto or a tenor, but a C-melody. It looks a lot like a tenor because of the curved neck, but the location of the B key (the first key above the bell seam) strongly suggests that it is a C-melody. To be sure, measure the length from the bottom of the bow to the neck receiver. If it's about 25" it's a C-melody. If it's closer to 30" it's a tenor. C-melody saxes haven't been in favor for a number of years, but they are experiencing something of a revival as a niche market. C-melody horns have a lower value than altos and tenors.
The big bummer with that horn is that the keywork is antiquated even by vintage horn standards. It lacks a front F bridge key, which is a big limitation for playing at the top end of the horn. It also has a button style G# keytouch, whch is really clunky to play. Bueschers of that era did have a single octave key, so you've at least got that much.
The horn looks like it's in reasonably good condition, but it's a horn for fanatics only. I honestly don't see a whole lot of value as a mainstream player's horn. Your best option would be marketing the horn to historical horn buffs on an as-is basis.
