========================
John from Saskatchewan, Canada, has a question about the Farm-Aid Implement Company from Norwalk, CA. John wanted to know more about the company or about the implement. I did a few searches, but all I could learn was that the company was sold in 1948 to Krause Plow. Anyone have any additional information about this rare disc equipment?
