Estate sale oddity

Saw this mando shaped instrument at an estate sale today and I figured I'd post a pic to see if anyone might help identify this old bowl back. It is in pretty rough shape (crack in the back and top, top separation, and tuner issues.)
It is set up with four courses of three strings each.
I didn't buy it as I feel it is beyond my limited repair capability. Don't have any idea where you'd find six on a side tuner plate. And I don't need another wall hanger!
No label, markings, or anything to indicate maker or country of origin.
Any thoughts from the bowl back crowd?

It's an old Oscar Schmidt- it has an OS monogram on the pickguard. I would imagine a gear and a post would be fine to fix that tuner strip. There was someone in Poland who was selling two brand new very old German six on a plate tuners a while back! Here is one with different tuners: https://jakewildwood.blogspot.com/20...-mandolin.html

It's a mandriola. Not all that unusual depending on where you live and who lived there before you :cool:

You could probably find an older set of those same tuners in 4 to a plate and scavenge to cog and post.

Added: They also use 6 on a plate tuners on 12-string guitars and I wouldn't be surprised if they were similar.

Mandriolas crop up frequently and in the US they are almost always OS's although I have seen other brands. You were wise to walk away especially at that price.

Thanks for the responses. Much as I was tempted (of course anything resembling a mandolin is tempting) this looked like too daunting to try to repair. The back separation, which I should have shown better, ran the entire length up the middle of the bowl. Oh well, ..........

I have heard them sometimes called a trichordia but I believe mandriola is the more accepted term.

I have one, here, and I play it now and again. Mine is tough to keep in tune (as I will be when I am over 100 years old). It is great for chords, very ringie as you can imagine. It is a compromise for any kind of melody playing.
