MF 202 Work Bull Tractormeter

I've got a 1958 202 Work Bull and I'm trying to determine if my tractormeter is original or is the original style.

I worked for a Massey Ferguson dealer back when the 202/203's were new. Work Bulls were industrial tractors, thus the yellow color. They have a heavier front axle than the MF-35, so the apple growers liked them, putting forks on both the front and the rear. The tachometer you show is original. We would remove the tachometer you have, and install the agricultural tach that showed PTO rpm and ground speed. We had a local machine shop build wide rear wheels and install 18.4x16A tires for a lower profile. We always had several new take-off industrial tachometers in the parts department. Many of those great tractors are still in service around here.
 
Thank you very much for that excellent information! My tractor seems mostly original, but given the age and unknown history you just don't know.

What are the dots on the meter at 1200 and 1300 rpm for? Is this where the engine torque is at its max? That is what I assumed, but never new for sure. My 62 Owners Manual doesn't say anything about this.
 
I'm sorry, but I don't know what those dots mean. I am in central Washington State, once The Apple Capital of the World, now the asphalt and McMansion Capital of the World. I don't remember any new tractor leaving without an agricultural tachometer, unless it was used as a loader/backhoe. Those owners just ran the engine until it sounded right and did the job. I doubt if any of them could even tell you what RPM they ran; they just throttled up until the needle pointed where it was last time they used it. If there ever were operator's manuals, any that survived would still be in pristine condition, never having been opened or read. My MF135 Perkins gas (same basic engine as the Work Bull 203) turns 1700 RPM to get 536 PTO RPM, but I don't know if your Continental engine uses the same gearing.
