Bud Ritter of Baltimore, Maryland......when I was getting back into the hobby in 1980 while I was an internal medicine resident at U Maryland Hospital, he was big help to me. He was a TCA member who was also a clerk at Antique Train & Toy World on Falls Rd (off I-83) in Baltimore. He spent endless hours answering my questions as I got back into the hobby......mostly filling in the gaps in my PostWar knowledge.
