Columbia Type N Graphophone Survey

[Tinfoilphono]

A year and a half ago I posted a thread soliciting information about Columbia Type N Graphophones in collections today.

 

I got over 50 responses, which I very much appreciated. But I'm sure there must be many more out there. I'd like to build a large enough database to be able to (hopefully) draw some statistically viable conclusions.

 

If you have an N, or a Thornward, in your collection, please post it here or if you prefer, email me at rene@rondeau.net with the following:

- serial number
- reproducer -- (gutta percha or aluminum?)
- on/off switch -- (stamped "SWITCH" or plain?)
- spring barrel -- (brass or cast iron?)

 

And any other details of interest.

 

If you have an N coin-op, I'd appreciate the following:

- serial number
- reproducer (gutta percha or aluminum? With side set screw or not?)
- crank (conventional or with winding gear mounted directly to crank shaft?)

 

If you have a Thornward, please indicate if the decal is rectangular or banner style.

 

Owner information will be kept confidential. 

 

Thanks for your help with this research project.
