Shimano 3 speed hub
I am refurbishing my 38 year old Moosburg 3 speed internal hub touring bike. It has not been ridden in 25 + years.
I have cleaned, lubed and polished the front hub and fork, front calipers, replaced pads. I am now to the back hub. The markings are chicken scratch and a Patent #, which leads to Shimano, likely a model 333 based on age and one article. I am familiar with the old Sturmy Archer AW hub, which I could rebuild blindfolded - 50 years ago! What I found on the 333 hub is not serviceable..
1. How do I service this hub? Are the bearings removable? Do I just add oil and clean the exterior?
2. The chain is in great need of a good cleaning. Somewhere I read to never reuse the master link. Is this true?

If your 3.3.3 hub has an oil port, add a little light oil. Likely it's gotten gummy inside from age and disuse. Use it and see how it works- likely it doesn't need anything.
Back in the day I would overhaul Shimano and Sturmey-Archer 3-speeds just for fun.
Many new master links for derailleur chains aren't reusable. On your chain it's OK to reuse as long as you like.

Bikes are okay, I guess.
