This is a great thread. I have been collecting gunsmithing books over the last 40 years - and some of those were a bit long in the tooth then... So, when I saw the thread, I went and looked through them for lube oil and greases. What they had was a mix of off the shelf stuff like Outers Gunslick, Hoppes oil, Outers oil and some custom stuff you could do yourself - Gulfoil (from your local Gulf Station) mixed 50/50 with sperm oil you could get from your local pharmacist (with Sperm Whales being on the endangered list, I don't think you can get it anymore). Sperm oil is specifically listed for cold area hunts - the stuff never gummed.
Reading Uncle Nick's post, I think that the old & arcane listings have been well updated. Great post - I will take some notes and give some of them a try.
Again, great thread.
