Midge was kind enough to get authorization about 10 years ago for all new couplers for my 1998 20-6519 Amtrak Amfleet set which had started crumbling do to zinc pest rot. I scanned the original receipt along with Emailing pictures to her. This kind of service which was provided to me gave me faith in MTH along with all the members on the forum providing advice on fixing small issues.
Thank you so much Midge!
