Anyone know where I could find one of these?

Can I put 30W in the inboard and outboard bearings on the old motor as well?

What type of oil do I use?

I've got a Brunner 939 air compressor in absolute original condition. I'm wanting to learn more about the compressor and how to keep it running for another 100 years. Can anyone help or point me in the right direction?
