There's all kinds of crazy theories out there.
The most coveted vintage Gibson electrics are the sunburst Les Paul standards from about 57-60. In reality, these were factory-equipped with *nylon* nuts, aluminum tailpieces, the early ABR-1 bridges without retaining wires (so you can look for the saddle and screw on a dark stage when a string breaks) The ABR-1 was mounted on 6-32 machine screws threaded directly into the wood, which had a tendency to lean over time from string pressure. The bodies were cemented together with phenol glue, which was radio-induction cured (literally radio-frequency electromagnetic radiation) not "hide glue" like everyone thinks. They also used aniline red dye, which bled into the binding and quickly faded on exposure to sunlight, even in store windows before they could be sold.
The wire was added to the ABR-1 to prevent loss of the saddles when changing a string or when one broke. They went to threaded inserts so they wouldn't tend lean over time and to improve manufacturability.
The tailpiece went to zinc as a cost saving measure.
The Nashville bridge allowed for more adjustment range, since not all the necks mated to bodies in the right place... But as a benefit, the saddle no longer came loose and pinged across dark stages, nor was there a crappy wire to rattle and buzz.
Then there's the whole rabbit hole of pickups too.
I have a Gibson 1960-R2 Custom Shop 60th anniversary Les Paul. It is awesome actually. 8lbs and about 2 ounces, single piece body and all the pure vintagy hoo-hah. But I have to say, it plays and sounds incredible. Totally nails that "a great Les Paul sounds like a beefy Telecaster" thing in spades.
There's really nothing wrong with the Schaller hardware or their humbucker pickups for that matter.
