If Arkie feels that strongly about dressin up thet old gal he must really love her an maybe accordian repair persons would have some tricks or at least be the ones to interview. The outside plates are easy to remove and re-chrome can be done easily (wount have the same feel). The risk however is quite large that any of this will alter the sound forever. Not worth the risk to my way o'thinkin. Old and vintage instruments have their own look and sound and don't get that way from settin around unused. Arkie likes the old sound and should also appreciate the look of wear and tear that has brought him and so many others so much pleasure thru the years. Bet he wouldn't trade her in fer a new one. Thets my drift. Cheers to Arkie!
