Apologies if this subject has already been covered. I recently bought some early electrical instruments whose previous owner was enthusiastic about polishing brass...very enthusiastic. Anybody have experience "re-tarnishing" brass?

There are products on line that set a patina on brass, copper etc. You can try white vinegar or lemon juice first. If the piece is off you can heat the brass and it will enhance a light brown patina. Just my experience with metal as I age copper and brass lamps. Good luck.

I use gun bluing and then buff it back to desired patina.

I am with Hoffies2 concerning the gun bluing.
You can also try soaking the escutcheon in a strong solution of just regular tea.

Hi streetmechanic14,
Rather than gun blueing (which is designed for steel) I would suggest Birchwood-Casey "Brass Black" which is designed for brass and copper. Available at sporting goods stores and from many online sources. Purchase the smallest bottle you can get, as a little goes a long way. Apply it like hoffies2 says, then buff it to get whatever patina you want. Overlay with a coat of clear lacquer.

Robert Lozier has very good results using JAX chemicals to redo escutcheons. The following thread has an explanation and a good example of how he restored a Temple escutcheon:
