Here's the "2a" with it's plano-reflex tonearm and No. 9 soundbox, for reference ... I've been doing a "soft-search" for this machine for a few years now. I'm fascinated by the single spring and what I presume is a fairly light and unique-sounding horn machine. From what Roger has written, I know he laments the sale of his. There is so scarcely little info about these. I *think* someone posted photos from a 1928 or 1929 Paris gramophone show, and at the Columbia booth, this machine can be seen. I can't seem to find it, though.Paolo_MK68 wrote: ↑Mon Apr 25, 2022 1:17 pm Thank you for the link and the nice words!
Definitey the assembly of the elbow and tone arm looks similar to that of the machine you pointed out to. Pardon my ignorance: does "Columbia Plano Reflex arm" means the typical arrangment with the short swiweling joint and the blunt tube elbows also found on later Columbia portables?
