How Tell if Triumph is 2 or 4 minute?

[rkruz]

I have an Edison Triumph s/n 63901 with model C reproducter. Did they just make 2 minute models or are all 2/4 minute? If 4 minutes, I dont see a way to change the speed.

Thanks

Check the pulley: if there's a section that can be pulled out or pushed in, it's 2/4 minute.
All Edisons were 2 minute only until 1908; but earlier models could be 'upgraded' with a combination attachment. I have a Triumph from 1902 (s/n 31900) that was so modified.
Also, does your machine have an endgate? Phonographs from 1908 or later do not, and are more likely to be 2/4 minute models. Photos would of course help.
If you do have a 2/4 minute machine, you might invest in a Model H reproducer to play 4 minute records. A Model C is for 2 minute records only.
