Massey built these things in the late 50's early 60's. Corn head and pickup headers optional (have a video of a corn head demonstration). Not enough power or capacity to combine corn, only a 25 bushel tank. I own an MF 35sp built in 1960 with a 7 foot header, plan on using it as a seed combine (most of these came with a scour kleen installed). Did some alfalfa with it last year - not bad! Think it requires some serious mods to work well, especially in the concave as it is badly bowed just from normal use. Only tried corn once, just to clean up some leftover stuff in the spring on a farm I had purchased - did the job but I wouldn't want to do it again.
