Pemaco brass and nickel plates the piano hardware (casters, hinges, pedals, etc) for the vintage Steinway & Sons pianos I restore. Most consider the Steinways built in the 1920-1930s as the finest the company ever made so the hardware also has to have the finest plating. I give them a set of rusty, corroded and filthy hardware pieces and they give them back sparkling and like new with a nickel or brass plating and polish. Theyre very reasonable but really do exceptional work. Ask for Jose.
