Back in the 1960s and '70s, when I was into racing cars rather than tinkering with 1911s, I bought the factory service manual for every car I owned. For most lubricants, they specified the SAE viscosity and for gear lubes a GL number ... but never a brand. Door hinges: "white lithium-based grease" ... but never a brand name.
For certain, very specific application, though, the factory manuals specified Lubriplate. I have always figured if it was the ONLY lubricant that I ever saw called out specifically by name in a bunch of books filled with lubrication specifications, there must be something ti it. I use it on the rails and locking lugs of 1911s. Brownells sells it, and they won't sell anything they aren't willing to stand behind.
