Questions re old Crescent bandsaw

I'm still setting up my "new" wood-shop.  My old band saw was built into the workbench of the old shop, and was marginal for re-sawing anyway, so I left it there for my son to use.

This summer I picked up an old Craftsman saw, which has cleaned up well... but which probably isn't any heavier-duty than my old machine.  So I recently bartered for an old 20" Crescent Machine Co saw.  Solidly built old thing, with simple design.  http://vintagemachinery.org has a lot of information, but most of what I've seen so far has been about acquiring & dating them... and not as much about the "care & feeding" of them.  A few questions:

[1] Babbitt bearings, which seem to be in reasonably good shape, have these peculiar-to-me oiling fixtures.  Can I just replace them with some little "lidded-cup" oilers, like are on some of my older motors?  And if so, what sort/weight of oil should I run in them?

[2] I found the number 28156 stamped in the end of the upper frame arm, which would seem to place this saw in the 1915-1920 range... again, guessing by what I see on the Vintage Machinery website.  Any guesses out there?   I also found the raised numbers 1847  on the babbitt housing for the upper wheel, which I assume is not a date, but don't know what it might be.

So far, I've removed the enormous wooden table the machine came with, and replaced it with a 20" x 24" plate of 1/4" steel.  I've ordered a .5"W blade x 3tpi [Olson brand], and some new urethane tires, and a set of replacement ball-bearings for rebuilding a different machine's blade guides.......I figure to fabricate guides of my own.  And then I'll also need to come up with a proper shield for the wheels and blade, to give at least a passing nod to safety.

keepin' on...
