I'd guess india. That style of plane has been coming from india for a few decades (india is cheaper than china for industrial work, too).
Somewhat famous for tools that can sometimes be used, and other times can't be physically possible to use.
If someone is wise enough to copy the basic stanley bailey pattern, the plane always has potential, even if the cap iron teeters on the adjuster dog or some other initial non-starter. I'd be tempted to see if I could get one of the ones like the plane shown in that video to within LN's flatness spec and working in less than an hour with all of the problems solved. The iron and cap iron are a wild card on planes like that, though. I had a later english stanley (really later, plastic handles) that had a gross casting and the adjuster yoke and pawl were way oversized - the cap iron couldn't fit down the paul. I fixed it. But the surprise of the whole thing was that the iron was quite nice. IT was coarsely milled, but in a good hardness range (probably 60 or so) and sharpened and worked nicely. I threw the rest of the plane away and no clue where the iron is, but I'm sure I still have it. It wasn't O1, but probably some euro 1.xx CV stuff (which is fine), but far better than any of the round top stanley irons that were common on type 20+ planes 30-40 years ago.
