Hello, I can remember looking through Farming Magazines throughout the 30's, 40's, & 50's, etc and coming upon Massey-Harris advertisements listing Dealers in Iowa. Many of them long gone today. Not every issue but occasionally. I have used that information on roadtrips chasing down leads. Many goose chases, but I have found enough to keep going. Check your local Farming Magazines, you might get lucky. I also checked other brands as well. Great trading stock to get what you might want. Tim Pace
