Newbie here with a question.
I've been "restoring" a Columbia Grafonola floor model. It's my first acoustic and the Mrs and I are loving it - so much so I've already purchased another acoustic - a flea market find late 40's Birch portable. (An obsession is born!)
The Grafonola plays very well (though the auto stop works a little too well - stopping 3 times per disc) and the majority of the work is just cosmetic (cabinet refinishing, missing screws, etc.,).
Here it is the day it came home with us:

The one stumbling block I've run across is that I've no idea what model it is!
From my research it appears to be an early one. It looks exactly like the 75 (I won an original instruction sheet for the 75 off eBay, and have seen old YMCA related ads for the 75 on Google), but I'm not 100% sure, mostly due to not being able to compare the storage systems. The manual has no mention of any storage system and there are no illustrations other than the cover.

Apparently a very similar 85 looks the same (as told to me by Great Lakes Antique Phonograph), but has the auto eject system, while the 75 the manual vertical slot system. Our Grafonola is missing such a system entirely (ripped out) except for one remaining slat - that could have gone in either.
Grafonola experts: Is this a 75, 85, or something else entirely? I'm toying with the idea of rebuilding a manual storage system as I was lucky to have received exact measurements of one employed in another model Grafonola, but if that is wrong for this one, perhaps not.
Note: I understand the out of print Columbia Phonograph Companion Volume II might be of help in my research, but even after contacting the author, I don't appear to be in luck of getting hold of a copy anytime soon.
