What brand tuners are these?

[Joe Strummer]

I found an unusual Kiwaya made uke that has these tuners. Are they friction instead of the usual planetary ones they use? Any idea of the brand, model, or vintage?

 

[Dohle]

Yes, those look like the same friction tuners Kamaka used to use before switching to Gotoh UPTs. I'm pretty sure those are Schaller friction tuners. I haven't tried them myself but haven't heard good things about them.

I fitted a set of those tuners to a cigar box uke, fourteen years ago. I forget the brand name. They were well made, and they worked fine, but I thought they were a bit big and bulky for a sop.
