A thread on a late model King Zephyr baritone got me to thinking - what is the longest known production run of a saxophone, with the same design? Changes in the name or changes in the engraving don't count - what I'm talking about is when the basic horn is the same - same mechanism, same acoustics. Here are some candidates -
Buescher 400 baritone - morphed into Bundy and then to Selmer USA, but the same horn (distinctive back-of-the bell placement of low keys).
King Zephyr baritone - from sometime in the 1930s to maybe even as late as 1980? It lost the fork Eb and gained a front F but the split-bell-keys remained to the end.
Conn 12M baritone - mid 30s maybe before, to maybe as late as 1980? I'm not sure whether the split-bell-key ones should be considered a different model than the same-side key models, because as far as I have ever been able to see from photos, it looks like every bit of the mechanism except for that one key was the same.
It's not surprising that new-model development lagged on baritones due to smaller production quantities.
Conn New Wonder tenor - the New Wonder 2 tenor (late 20s?) appears to have been converted into the 16M, which continued clear through the Mexi-Conn days. My late 70s Mexi-conn tenor appears identical to a NW2 except for engraving, a few key touch shapes, and a few other minor details.
