Harmony talking machine NEED HELP

Hi
At a local auction next week they have this Harmony Talking Machine made by Great Northern MFG. co. I have searched the web and have found nothing on it. Does anyone here know anything about it and also the value on it. Thanks

There's a little bit of info here-

These are like "standard's", which have an enlarged spindle, designed to try and force buyers to only buy harmony records. Generally, Harmony and Standard machines go for less than other phonographs like victors because of this. The records are harder to find, though they do turn up on ebay from time to time. Some collectors also get the spindle turned down to the standard size, so they can play normal 78's, and have an adaptor made to fit harmony records. From memory, they usually go for around $400, but I could be wrong. My memories not what it used to be

Heres an earlier model, which is for sale at 1250 euro's, but i think thats more expencive than usual. It might be worth a look on ebay, as they do come up on there now and then.

I just found another site, which says they sold one on the last day of their half price sale, for $175

The Harmonys, like the Standards and Busy Bees, were client machines made by Columbia Phonograph Co. and distributed by the Great Northern Mfg. Co. of Chicago starting in 1907. Unfortunately, with the 3/4" spindle, you either bought their records or used an adaptor to play their discs on standard size spindles as previously mentioned.
