Well, if professionally overhauled, the price divided by two for the gold one is not terrible.
But the silver one is somewhat 'common' fare.
FWIW Chu prices have fallen considerably over the years. Here in teh states one can usually find a silverplate one in good, serviced shape for around $850 these days (that is what I usually sell them for). The Tenors are more sought after.
Doesn't much matter, IMHO, whether the gold-plate one is original or a replate, it is quite beautiful. I could see a seller asking over $1g for that one. Of someone paid $1300 for it, I would not say they were foolish. But all in all, for both ? $21-2200 tops, so that is significantly less than the £2500 asking price.
Gotta ask if the microtuners are fully working.
Then you gotta consider the New Wonder Alto Gurgle. Do you want to potentially deal with that ?
Sometimes the...dynamic... starts out being absent, then it shows up...it is not a leak, or if it is a leak, it is often a leak which would be inconsequential on 95% of other saxes.
It is the design of the bow geometry. Usually alleviated by a wine cork tossed down the bell...or a more permanent solution being a piece of brass tubing soldered to the inside of the bow.
yeah, yeah, yeah...some owners will chime in and say they never had that problem. I believe that 100%. But they are in the minority. Having refurbished at least 25+ of 'em, I can tell you it is an intrinsic thing. Not a killer, but....can be annoying, IMHO.
Chu's are cool.
I would rather own a Buescher TT, and I would steer anyone looking for a splitbell alto in the TT direction, myself.
If what they desire is a Conn alto, I steer them towards a 6M...the non-rth-but-still-Lady ones are comparably priced to the Chus.
