I rarely have a need for a 1/2" drive chrome set since most all my needs are met by my 1/2" drive heavy duty impact swivel sets. That said, there are a few instances on a Jaguar engine and transmission when a 1/2" chrome universal is the only tool thin enough to get the job done. I've used 3/8" drive chrome universals up to now, but the force necessary to loosen the fasteners is often quite high.
Finding a nice US made 1/2" drive 6 point chrome set for a reasonable price is next to impossible; even on e-bay. Best I found so far was older MAC or Herbrand sets on ebay that still sell for close to $100. So when this set popped up on eBay a few years ago I jumped on it.
It's looks to be vintage 1980's/90's Taiwanese manufacture. The chrome isn't as good as current Taiwaese offerings; in fact the chrome looks like present day Craftsman quality. However, the fit/finish is very good and I'm quite happy for getting this set for $8.00
For a half dozen times in a year that I require chrome 1/2" drive universal sockets, this set will do nicely.
