In answer to my own question posed yesterday, "WHICH ZEPHYR", I offer the following.
I have 4 King tenors, 228,xxx '39-'40(which I have concluded is a ZS), 276,xxx a Zeph made in '46, 402,xxx a late Cleveland Zeph made in 1965, and 411,xxx, an S20, also a late Cleveland instrument of the same vintage.
The following measurements are by micrometer: diameter of throat=27.88mm; body tube just above join with bell= 6.07 cm.; bell just above join with bow=7.2cm. for Zs, 7.1 cm. for S20 (this 1 mm is likely simply my error in measurement); bell flare= 15.2 cm. for '40 and '46 Zs, and 15.7 cm. for S20, and later Z. They are the same for all save as noted!!
My conclusion: At least for the instruments measured, the ONLY DIFFERENCE IN THE PHYSICAL DIMENSIONS IS THE TRIVIAL DIFFERENCE IN BELL FLARE. The necks may be, and are different ( save the ZS and '46 Z which are both double socket, the former sterling, the latter brass and are interchangeable).
Hope this adds some fuel to the debate.
Regards to all.
