Need help identifying a bari uke

I won this on eBay and it arrived today. I'm trying to figure out who may have made it but so far I haven't really found anything. There are no identifying marks that I can see anywhere. Pretty sure it's solid mahogany, typical friction tuners, bone nut and saddle, and roswewood board and bridge. The soundhole rosette is inlaid. Probably not Harmony or Silvertone since I own a Harmony bari and 2 Silvertone baris. Anyone have any idea?

Looks similar to a 1960's Vega...but the bridge looks kind of Harmony-ish...

Made in Japan is a possibility too...

I think you're correct on the time frame it was made and where. Definitely not a Vega but very similar. Thanks I do appreciate it.
