Help ID this 3 pt. Mower? (pics)

A guy I know has this mower that he got when he bought 5 acres and an old homestead. It has been stuck in the dirt for several years and he just pulled it out yesterday and put it on the pallet.
You can see where there were 2 different mfgr/model plates rivited on but they are both gone.
Most of the sickle teeth say Ford on them and it does have a wee bit of blue paint in one corner though the machine has obviously been repainted a time or two.
It looks pretty complete to me but there may be some other bracket on the tractor that is missing.
We talked a little about doing some sort of horse trading on it but mostly We'd like to know what brand it is so we can look for a manual to help figure out how to mount it.
Sorry but I'm a better carpenter than photographer.
If someone recognizes the brand maybe they can let me know if they were a good machine or not.
The sickle is 6' btw. Thanks to Any and All

P.S. the best thing is to junk it and get a 501 Ford mower much easer to mount on tractor.

If it is a Ford it would it would probably out of the old Dearborn line. The pittmand type Ford mowers changed very little from the mid fifties to the seventies. Other mowers that would have been red and built for a 3-pt hitch in the fifties might be Massey Harris/Ferguson and New Holland. Remember that the Ford and Ferguson were the only 3-pt hitches as we know them today until the late fifties and early sixties. There were a few variants such as the Eagle hitch and JDs three point hitch. Look on some of the Ford N pages and check out the old advertisements showing the implement lines. Good Luck.
