Went to an auction near Rockford IL last Sat. They has a nice MM 1200 Shellmaster. It was complete, not rusted out or dented. Still had the original lettering and 40ft of drags. Went for about $1400, which I thought was high. But two people wanted it. Talked to the owner's son the next day and said his dad had been trying to sell it for a year for $500. Guess they made out OK. Didn't need another one; already have a working D and E, but not that nice.
BTW- At Paris IN, Mcgrew has a late MM sheller for $2500 on FleaBay. Check it out. Looks like new. Think Spring!
Sorry, didn't hear those sold. Bought two old gravity boxes for picking and was in a hurry to get one home (70 mi). I think the winning bidder of the sheller may have others at home in WI.
