yes Del Manges drove in western NY and his sons Larry and Brian also drove.
Red and white colors with a big "M" on the back, I believe.
Del Manges had five sons and you are right Brian and Larry were active, some years ago, as driver/trainers. At present, last I know, one of the sons (Dean) is a H.S. teacher in NC, Randy is the GM of the KY Standardbred Sales Co., Gene is a caretaker at Buffalo Raceway, Larry is retired from racing in Wilmington, DE, and Brian is the DE state official horse identifier.
