If it were me, I'd be on the phone demanding a return, if the operator plays the corporate 'no return' play line, I'd demand to talk to her boss, maybe even up to Larry Potterfield himself. No excuse for sending a buyer something in that condition if it is rust. As 'Sam' posted, sure it isn't red grease? I bought a new Pietta 44 US Marshall from EMF not long ago and there appeared to be rust in two of the cylinders. Called the California office as I didn't want to tear down and void any warranty. Guy at EMF advised to check if it was loose material as sometimes when the factory polish's the cylinders, they don't get all of the red rouge out. He advised to call back if rust. Checked, sure enough, dried red rouge material, cleaned up, cylinder was bright and shiny.
