Combines K serial n

Most Gleaners are on the left side under the engine above the shoe area. I have seen oil changes get them greasy_dirty or the breather tube in the area on some combines(not necessarily the K),plate is welded or riveted on with your numbers.

Thank you very much. That was exactly where I found it ... after I did a fair amount of wiping off.

The serial number is located at the left rear sidewall right beneath the engine about 4 feet above ground level.
