Here is a large 2 page ad in the Saturday Evening Post dated Sep 14, 1912 offering the new Columbia Eclipse. Large images are posted online at:

Note the reproducer, a Concert??

Interesting that is offer includes the double sided demonstration record free "beginning with the day of issue of this Saturday Evening Post and continuing for 30 days"

Nice ad. This is the early Eclipse with the one piece nickle plated brass tone arm, and a 10" turntable. Yes, that is a Columbia Concert reproducer. I like these early Grafonolas because they still use outside horn parts, and no pot metal.
Harvey Kravitz

Didn't they use what they called the "Analyzing Reproducer", did this have a mica or aluminum diaphragm?

The Analyzing reproducer is the early one that used the spring loaded clamp. The earliest ones had a thumbscrew until Victor sued Columbia over the patent. The Columbia Concert used either Mica or a pleated Aluminum diaphragm. I have seen them both ways.
Harvey Kravitz

I'll defer to Harvey on Columbia taxonomy, but Columbia seemed to transition through overlapping uses of tone-arms and reproducers...

The Analyzing reproducers I've seen, mounted to the tone-arm via three screws, from the arm into the backside of the reproducer head.

When Columbia came-out with the "Concert" and #5 reproducers, there were versions that also mounted via three screws from the back-side, but there was also an adapter flange with the first version of the bayonet-hub on one side, and a round flange drilled and tapped to accept three machine screws, but these were staggered "out of clock" with the screw-holes for the reproducer... in-between was a special rubber isolator, with six holes moulded into it, three to attach the isolator to the reproducer, and the other three to mount the isolator to the tone-arm.

I have / have seen Concert and # 5 Columbia reproducers set-up this way.

By about 1912 or 13, Columbia was casting reproducer bodies with an integral bayonet hub.


Also, the first-generation bayonet hub / receiver are slightly smaller than the later ones... later reproducers are a VERY tight fit in the early tone-arms ( as in, don't try it - the early arms are thin sheet-brass, "wrapped", and butt-soldered. Fragile`, as the Old Man would say).

A local phonograph buddy has two Eclipses, both slightly later than this ad version, one in oak, and the other in mahogany.
