Well Spooky it's this away...
The second link is dead. All I got was an error message. The first one still seems to be around though.
The seller didn't specify who made the parts, but he sure does like to impress you with "tactical" and all that stuff.
Some folks like to think that if they put the parts in a box (along with somebody's frame) they can shake it and a complete, functional gun will fall out. Most of the time it doesn't work that way.
I suspect that the seller doesn't have $200.00 in that collection, and whoever made the stuff had even less. I'd bet that most of it, including the extractor, sear, hammer, safety lock, disconector - and maybe even the slide are investment castings. I don't even want to think about the barrel. Truly good castings aren't so bad (look at Ruger) but they also aren't inexpensive.
John Browning's almost 100 year-old design depends on high-quality parts machined out of high-carbon steel and heat-treated to certain specifications. It also required that the workers that put them together have some experience and knowledge about how exactly to do it. Current day makers have tried to get around this by using technology Browning never thought of, and it shows in the many posts and threads on this and other forums from people that have bought a new (fill in the blank) 1911 pistol, and it simply won't work. Usually poor quality parts combined with sloppy workmanship and lack of inspection are to blame.
I can understand why you'd like to find an inexpensive .45 pistol, for as you put it - "... just a functional 1911 for knock-around use and backpacking duty. The only real quality I'm looking for is reliability;" but I think if you go this route you'll end up being disapointed. If I was in your shoes I'd look at Ruger and CZ-USA.
At least you'd know who made the parts, and what they were made out of.
