mystery shower fixture brand?

The water mixer on my shower fixture needs to be replaced (it's the lower brass portion in the attached photo). The problem is that no one seems to have heard of the brand. The only marking or name I can find is SOL. Has anyone ever heard of that company or have any idea where I can find it? There's a thread from last August on this site, where someone had the exact same problem--but the solution is not clear. I'd be grateful for any help at all. Thanks.

It is an Italian Brand...
"Lada"

Good luck finding parts for it!

The last poster got lucky!
