Farmall Regular Questions

I just recently acquired a Farmall Regular. It is definitely a project. It is missing several parts and needs lot's of work. Upon initial inspection, we have come up with several questions I hope someone can help with.

1. It is missing the data plate on the tool box. Is there any way to tell what year it was manufactured?

2. There are two levers under the steering wheel. One looks as if it might have gone to the magneto (which is missing). Was this one for spark advance?

3. The other lever's rod extends out toward where the radiator once was. Did it go to radiator louvers?

4. It has an oil filter on the right hand side of the engine that is plumbed in with tubing. I don't see this in any pictures so far. Was this an option, or an aftermarket add-on, or just something someone cobbled up?

I'm sure there will be other questions later, but these things came to mind when looking her over the first time.

It appears mine has been converted to the governor, as it has the notched rod going down the right hand side of the engine.

I'm not sure of the make of the oil filter, but it looks very similar to the Purolator on our "H", so it may well be original. I'll have to look to see if I can make out a manufacturer.

There is a serial number on the left frame rail up by the radiator, or where the radiator would go if she had one. I wrote down the number last night, but did not bring it with me to work. I'll get it later and see if I can find a serial number listing.

Thanks again to all who responded.
