Thanks for the kind words, Cody...
It is kind of hard to certain of much in Columbia-land...
If the arm on that Nopareil matches that early #6, it is probably brass. I believe the brass bayonet arms have a small limit-screw through the back-side of the elbow, when this is removed, the arm will swing-up vertically, and pop-out of the elbow.
The pot-metal arms are usually secured via a spring-ring that snaps into a groove inside the elbow.
The Nonpareil you referenced in the other TMF thread, from Matt Brown down in Reading, was a first-version, with the "victrola" horn-doors.
By about 1912, or so, Columbia had settled into a fairly uniform complement of hardware / motors. The spring-motors usually shared the same basic frame and bed-plate, but could accommodate anywhere from one to four spring barrels. The bayonet-joint tone-arm and # 6 reproducer were used across the line into the 1920's.
The major differences were in cabinet-styles, finishes, and type of record storage.
Thank goodness for Baumbach and Lackey's Columbia Phonograph Companion Vol 2, which at least gives a pretty complete listing of the disc phonograph offering from 1901 through the Viva-Tonal era, but it does not show all the subtle cabinet variations.
Many collectors feel that there's no way Columbia machines compare with Victor, and they probably have a good case - Victor products were over-engineered (?) and over-built to a fault... but I feel that Columbia still made some decent quality and attractive machines...
I have a "200" ( formerly "Deluxe" ) in American Walnut with gold plating, that is simply stunning.
I have at least a half-dozen Columbia uprights, some of which I have yet to positively identify: Leader, Mignonette, Nonpareil, Mignon, 100, 150, 200 ????
I hope these machines in Worcester find good homes !
