INTERESTING FACTS :  Although in many ways just another Model C Gem, except this one was sold as an ICS,   (International Correspondence School), machine. To condense the lesson given by a particular cylinder, the playback speed was reduced. Notice the large mandrel pulley meant to change the ratio and therefore the rotational speed of the cylinder. I do not know, however, what the new playback time would be. Three minutes? Four minutes? It also means that standard cylinders will not play at their correct speed. This machine could easily be converted to standard playback by simply swapping out the mandrel with a "normal" one. However, I did not want to change the special nature of this machine. I think it's probably fairly rare as it is, but perhaps not especially valuable.

Since the serial number falls outside of the range mentioned by George P. in his excellent Gem article published in the June, 2023, edition of "The Antique Phonograph", I assume it may be made as late as 1910, a possibility that George goes on to state in that same article.

 

I'll also note that this example is in pristine condition, leading me to believe that any intended lessons "taught" by this machine did not get very far. Sort of like most treadmills and excercise bikes...

Jerry,

Aside from the interesting (and undoubtedly scarce) ICS pulley on that mandrel, the beautiful condition of that Gem makes it a real standout!  So that's what they looked like when they left the factory...

That's a wonderful machine. I wouldn't dream of changing the mandrel. We all have plenty of machines capable of playing 2-minute cylinders. This Gem's history as an ICS-dedicated phonograph is just one thing that makes it very special. Plus, of course, its condition. This is something to treasure and only demonstrate with ICS records. What a stunning and historic phonograph!

I have a Model C with the same pully configuration, s/n 312936C, although not as mint as Jerry's.

Thanks for the great comments!

I didn't know there was such an adapted GEM in existence Jerry.  Even without the ICS configuration, the condition is really excellent.  I agree with you regarding not converting it to play regular cylinders.  I wouldn't either.  Even if you kept the larger mandrel pully with the intent of converting it back later, it could be misplaced.  Also, why take apart such a clean machine if you don't have to!
