Welcome, Preston.
I see you collect oscillators
I restored an HP200 about 2 years back.....plus a couple of SG8 RF ones.
As for cleaning the brass:
Ketchup is neat.
The secret is the acid.
Same results are obtained using vinegar and salt.
Ketchup is a paste so it does not run, and provides nice cleaning action, and so will the vinegar/salt mix, which is mixed with flour and water, creating the paste that does not run.
So will do the lemon juice. One way is to take half of the lemon, dip it in salt and rub the surface of the brass object to be cleaned. Keep dipping the lemon in salt as needed. Use table salt, it is fine and won't scratch.
PS. After the ketchup has done its work, it needs to be licked off. This creates a gastronomic pleasure along with the aesthetic one from watching a cleaned brass surface

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
