What's this from? 2

[JStephen]

Big piston rod seen alongside the road- picture with bike is for scale.
So what did this come out of? We're not anywhere near the coast, so nautical origins are unlikely.
It doesn't look that heavily built for its size, which makes me wonder if it's maybe out of a compressor instead of an engine. Did they ever make natural-gas compressors big enough to use something like this?

btrueblood may be on the right track as this could very well be a 'pitman arm' from a pump jack well, particularly since this artifact was found in the 'oil patch':

Yup looks pretty much like this?

There aren't many photos which have two bearings, but this one claims to be from East Texas

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Yea, I also had trouble finding a clear photo, which is why I went with the diagram as it showed something closer to what a true 'pitman arm' scheme would look like.

At least we came to the same conclusion!
