Ford 101 3 bottom.
It is missing the coulters and should have the same exact tail wheel as the older Dearborns.
The bottoms have a shear bolt on them so rather than bend or break a beam it will shear the bolt and trip that bottom.
The handle is bent on that one and should be farther to the plow's right.
It is for adjusting the plow to fit the width of the tire spacing on the tractor.
All the Dearborn and Ferguson plows had that feature too but required you loosen bolts and move the hitch pins side to side.
These you just move the handle.
They were built in 1,2,3 and 4 bottom though the 4 bottom was what they callsed "semi mounted". They came in 10,12,14 and 16" widths and were around for enough years they they came both in Red and Blue - I'm guesing maybe 1958 till into the late 60s or even in to the 70s.
You will often find a 3 bottom for less $ than a 2 as many folks don't know it is easy to drop the center bottom and have a 2. Shares, shins and moldboards are readily available - shares and shins especially can be had at Tractor Supply etc.
Below is a better photo of that same plow in Blue. Note the handle is not bent over.
