I went last year, there was not much in terms of Model A parts. I'd guess 90% of the vendors were not model A. I did not see a single zenith carburetor and saw one original distributor, a few old shocks.
Did you know the Nichols family? Stanbury Nichols DDS, was a member of a multi generation family of Dentist's in Medina. Nichols Family Dentistry still going strong with his son Will and grand daughter Kate running things today. I believe they are on Court St. Great family history in a lovely N.E. Ohio town.
