Hello
@Plum Creek,
Your "new" machine doesn't look much worse than mine when I first found it:

I spent extra care cleaning the sand and dirt out of all the oil channels that the wasps had left behind....vacuum, wire, wire "bottle" brushes, pipe cleaners and lots of rags and time!
I started by going over the machine and removing the loose crud and hitting every moving part and oil hole with a 50/50 mix of ATF (automatic transmission fluid) and acetone. If you can let whatever is stuck sit with that on, and even refreshing the fluid for a few days, you might be able to loosen things up.
Once things were loose I switched over to ISO-32 tractor hydraulic oil. I bought some old sight-glass, drip-feed oilers and some new gits type oilers.
I slowly learned all the controls while still turning the flywheel by hand.
I am not sure how the Cincinnati "LL" differs from the other models......are you?
There are a few manuals here:

and at least some of that should apply to your machine, because mine was made in 1916 and is very similar to those manuals is some respects.
Good Luck, and please keep us informed!
