I know of a MM model 250 for sale near fairfax, MN. It is is very good condition tucked away in the back of a shed. The people are selling everything out because the owner went into the nursing home. They think he bought it brand new and didnt put a lot of hours on it. There is still factory paint on the drive chains, I do not think it has seen much use, just his small farm. It is a 2 row pull type. A scrapper offered them $200 for it, they dont want to scrap it but so far that is the best offer they have. I would hate to see such a well preserved machine scrapped, so I told them that I would try to post it on some collector websites to see if anyone was interested in it. They said they would wait a month before scrapping it. ( a month from June 19) so if anyone in southern MN would like a nice MM model 250 let me know. They said they might take a reasonable lower offer if someone was going to collect it or use it instead of scrapping it.
