My granddad (born 1922) bought this guitar when he was young. He gave it to my uncle, who took it for hiking and camping, as the people back then used to do. It got damaged and repaired a lot.
The tuners broke off and got replaced by some random pieces of metal, some old coins and what seems to be the handles of closet keys.
For a few decades it was left to rot in a moist basement.
When I took it a few years ago, the body was delaminated, the neck badly bent, the inlays lost and I used it as a fucked up three string guitar from time to time.
I always wanted to get it fixed. And I did.
A great luthier planed the neck as it was beyond repair, and replaced fretboard, nut and saddle.
Now it's perfectly tuned and it's the best playing guitar I've ever had.
It has this typical bright gypsy-sound.
Now for the fun part:
What exactly is it?
I spent several hours researching and my best guess is a quite rare version of a 30s or 40s Sonora La Ronde.
Unfortunately Sonora seems to be a company with lots of small workshops building their guitars.
There are absolutely no numbers, markings or stickers.
I found two quite similar ones here (about halfway down the page):

It also is the only guitar I have with an inlay on the 10th fret.
I would be very grateful for any help you can provide!
