Microtuners, Rolled Tone Holes, Nickel Plated Keywork
Read a good write up here: http://www.saxgourmet.com/conn__saxophones.htm on Conn Saxophones.
The article states: (Last ||P)
"... The saxophones lost their rolled tone holes in 1948; and their Microtuners in 1954. The professional models gained nickel plated keywork in 1955, along with clear lacquer. The tenor neck was changed significantly in the late 1950’s to an underslung design, but by then it was too late. In 1960, Conn acquired the Best Manufacturing Company of Nogales, Arizona, and moved most saxophone production there, although the “artist” models continued to be produced in Elkhart. The company has undergone several changes in ownership, and discontinued professional models in 1970."
ROLLED TONE HOLES:
(1) Is (1948) around the time (all or most) saxophone makers ended the (rolled tone holes) or Conn only?
(2) I haven't come up with much information regarding the (Microtuners)
(a) Was Conn the only horn company who employed or created this design?
(b) The article states the microtuners design ended around (1954). When did it start?
NICKEL PLATED KEYWORK:
(3) The write up states: Nickel plated keywork has its beginning around (1954).
Is this true for Conn horns only-- or other horns lines as well?
