To me condition (and therefore usefulness) is a much bigger concern than who made it. I'd rather have an "unheard of brand" lathe with little spindle runout and ways that are tight for the entire length than a sloppy well-known name. You can do so much more with it.....if it doesn't need major parts.
Of course in the real-world it's usually not one or the other but somewhere on the spectrum and you must consider cost, condition, accessories, availability, space, weight, size, knowledge, etc.
Wobbles is right about ballpark cost for my local market, too.
The lathe above looks mostly complete, maybe excusing change gears, but even if odd-ball gears they can be made at home (with some additional equipment). Sure it is nice to know the manufacturer so that you can look up what face-angle the gear teeth are, but really once you have it you can figure it out and then seek/make more.
The manufacturer will reveal itself eventually......I'm actually a little surprised that no one has positively identified it yet.
I suspect the right person has not read this thread yet.
Good Luck!
