[78-L] 12" Edison Sample Records

[Clifford Bolling]

Just brought home an Edison C250 today that had 3-12" sample records inside, Nos. 9, 10, & 11.  I've heard about them but these are the first I've seen.  Seems there isn't a lot of info floating around about these.  Are they scarce/rare?  How high does the series go?  Beyond 11?  How frequently were they issued?  Stuff like that.

The 2 drawers were full of Diamond Discs and more than half had their original sleeves with stickers describing the artists and songs, all with the embossed labels.  I think this bunch of records is original to the machine.  Very cool!

There were also a few of the 57000 series (german).  

Any info would be appreciated.  Thanks!  CDB
