Mike's work is the best. The parts you have him do will be as nice as Stashyboy showed in his photos above.
One word of advice - be sensitive to what you are having him do for you. All of the plating on exposed parts on Gottlieb EM games was nickel plating, not chrome plating, with the exception of the lock bar end caps that started this thread. I, mistakenly, had Mike replate several of the receiver channels that reside below the playfield glass and above the playfield at the rear of the playfield. I naively had him chrome plate them. As soon as I put one in the game it looked wrong. In the end I sent them back to him and paid him to redo them in nickel plating. Now they look right. This is just my anal retentive opinion. I like these games to look original. Chrome plating stands out as not original on most of these parts.
