"25m was a 24m with high F#" ???
It’s just ridiculous to read:"King 660=Conn 24M=Conn 25M=Conn 4M"
These are completely different saxophones, and it’s possible that the Conn 4M is made from a different metal to the Conn 25M. The sound is different. Does your logic suggest that 90% of the Chinese saxophones on AliExpress are Selmer SA models?
I am afraid you are likely incorrect... and I'd appreciate e a bit more respect in your semantics, please.
You were the one who gave the measurements....TWICE I asked for MORE measurements and you have yet to provide those.
So BASED UPON YOUR FEW measurements....the 4m and 25m appear to have identical specs.
I am 90% certain the 25m body is a 24m body with a high F# hole. By all means, you can prove me wrong if you get ahold of a 24m and measure it.
Am also 90% sure a 24m IS a King Empire (660).
Again this is from my experiences of working on ALL THESE MODELS (except the 4m which I have never even seen).
So while I appreciate your posts and contributions...if you want to prove someone's assertion as....'ridiculous'....take a calipers to the models in question and measure in MORE THAN four or five places, and post those measurements here.
I am fine with being wrong, but you gotta do more than just insist with no numbers backing it up, is all.
I have no clue why you brought up fake Selmers and AliExpress...are we discussing that here ?
When you then state 'different metals because they sound different'....you are on such shaky ground that it is probably wise not to go there in this thread...
Maybe they sound different because the neck tube is different ? (We could know this if you would provide us with more neck info as I illustrated above). Maybe it sounds different because the bowpieces are different ? Or the body tube holes or taper....?
We dunno, because you have not provided those measurements...and you are the guy with all those horns, currently.
UMI's Conn 34m and King 662 appear to have been the same horn, just rebranded. They may well both be an Armstrong 3055 as well...Other Armstrongs are identical to the Conn 22m....so....
Yamaha has been the Master of such stuff for over a generation...a 475 was a 52, renamed. A 52 first series was a 23 with a different bow, neck, and pinky table. A 34 was a 62 with a 475 neck and no ribs or annealed bell. A 575 was a 62 with a 62 neck and no ribs or annealed bell.
Jupiter 667/9 and 767/9 are the same design just the latter has the high F#. Jupiter Carnegie seems to be a 767 under a different model name. Jupiter Capital Edition is just a 767 with a sterling neck....so, interestingly, Jupe rolled off three different models with identical body geometries and key designs....
This stuff has been going on for ages...
