I will readily confess considerable ignorance regarding M-H agricultural equipment, but I am familiar with tanks, including those built by M-H.
Should you have questions, feel free to reach out to me, I'll try to help. My email address is ddoyle9570 at aol.com
In the interim, I'd sure like to establish email communication with John Farnworth - where would I find his email address?
(author of one book on John Deere, and a couple of dozen books about tanks)
