A-250 Edison Diamond Disc and the Laboratory model badge

[DGPros]

As far as the badge signifying the 250 being the laboratory model, didn't that start in the later years, as in C-250? http://www.ebay.com/itm/Edison-A250-Pho ... Sw9~RXJAPs

I highly suspect that the medallion came from a later machine.

As far as one can tell, the earliest medallions were used on the late B250: they were pentagonal, with much different wording.

Yes agreed.

I have a A250 with the s/n 14,444 and it does not have a badge. I have a couple of B250's but none of them have a badge. I do remember seeing the earlier style badge Bill is speaking of, but it was in a display case.

Fran Pratt's upcoming installment of his landmark work on the C 250/C 19 (which will appear in the June issue of The Antique Phonograph) shows all known variations of the medallion. The circumstances surrounding the medallion's appearance on certain late B 250s will also be explained.

Thanks for the responses and that's what I had surmised. Nothing else looks out of the ordinary on the machine, at least to my eyes. I am looking forward to Fran's next few articles, as well as everything else found in the publication.

Some C-250 and C-19 Laboratory Model Medallion examples..

1. Early C-250 Laboratory Model example Medallion

2. Late C-250 Transitional Laboratory Model example Medallion

3. C-19 Model Laboratory Model example Medallion

The Early Pentagram Medallions were simply screwed in by 3 obvious screws. The later Circular Medallions such as #2 and #3 were held in place by a long pin in the center of the medallion on the reverse side. It was simply "pushed" into the wood, and that held it in place.
