Columbia N Survey
Posted: Thu Nov 03, 2022 4:27 pm
A year and a half ago I posted a thread soliciting information about Columbia Type N Graphophones in collections today (viewtopic.php?f=2&t=49077). 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 [email protected] 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.
