I googled Carl Appel and found an obit from June 1997. He apparently lived in Coopersburg and owned Appel's Jewelry in Allentown. http://articles.mcall.com/1997-06-25/news/3140250_1_big-game-east-africa-allentown-elks-club

That's too funny, I just replied to the OO thread on the main section and mentioned Carl. He had a rather large OO layout back in the day which was featured in MR at least once. Appel Jewelers is still in business in Allentown. Very well known to locals.

If you have access to MR's digital archive (or otherwise have access to the issue) check out the November 1958 issue of MR for an article on his Norfolk & Ohio layout, preceded by a truly impressive photo that takes up two pages; one of the more realistic photos ever published in MR.
