Thread: Rifle re-bluing

Hi, I’m considering a refurb on an old air rifle I have; I know it’s pricey but I’d like to have it reblued properly.
I’ve been given a contact for the bluing but they don’t do the metal prep - are there any suggestions for metal polishing companies that work on firearms?
Or suggestions of companies that will prep the rifle and blue?
Below are pics of the rifle and a reblued one for reference.
