Agreed. Back in the late 1870's the Swiss Federal government formalised the mix of tallow and other naturally-derived lubricants to use not only as lubes, but also cleaning agents for their new breech-loading small-arms. Being Swiss, they adopted the natty title of 'waffenfett' - 'gun grease'. Catchy, huh?
They continued to use that, and NOTHING else, as lubricant, cleaner and preservative on ALL their small-arms until the adoption, in 1957, of a self-loading rifle. Due to the stresses and strains involved in the action, it was felt necessary to add a spiffy newly-developed ingredient that made it black and VERY messy in use.
Again, that great Swiss comedic trait came out, and since it was designed for automatic weapons, they gave it the catchy title of 'automatenfett' - automatic gun grease.
Here's the skinny from our dear and much missed friend of all things Swiss - Frank van Binnendijk - AKA Guisan - in answer to a question about the use and properties of the 'black stuff'...
..I don't think it's that simple, although the Molybdenum Disulfide is an important content it also has it's weak points as it binds with moisture and that is something we don't want in guns, the auto parts grease was made for cars and not for guns.
The PDF sheet reads that the grease is made to the armies requirements and it is not the complete recipe, it only lists viscocity, melting point, some of the ingredients and a few other things but that is more as we ever knew before.
Mike besides the old yellow grease I have nothing to compare it with so I don't know.
I found a little more also but that was less interesting...

It's more about how to clean it off and if toxic (not).
I have three Swiss unmentionables, one dates from 1914, and is a conversion of a 1900-made rifle, the other dates from 1944. The odd one out is a 300m match rifle that uses a 1954 action. All are utterly indistinguishable from new from one end of the barrel to the other - all kept like that using nothing more than *'sheep grease'.
