I have an original OD Burnside with the original bearing from like 12 years ago. Played (somewhat) often and still good as new. You are correct.
On your comment about Mineraloil (Sorry, yesterday I was swept away by the string and bearing talk).
When I talk about Mineraloil, i mean brake-fluide for Shimano hydraulic brakes. It’s thin as water, if not thinner, thinner than sweing-machine oil or fine mechanics oil. And it lubricates like a mot*erf**er. A small drop will make a man fall, as I witnessed in said bike-shop.
So no mineral motoroil, if you thought about that. 
Edit: I would not use Shram or Magura DOT fluids, they are hydrophilic.
