Okay I see it now. As though they pounded a pin in, then ground the ends off. That would explain the surrounding texture. Here's a view of each side

      

Yes, that is probably a tapered pin. Be sure to drive it out from the small end. I would measure the ends with a vernier to determine the small end. Support the shaft end well and drive it out with a drift punch.

As others pointed out, proceed with caution as not done correctly could end poorly.

I remember years ago, someone on a gun forum said he always took high res pics of his new used guns. He said the photos showed way more than the naked eye.  I bet these don't show up as well in person as they do in the pics.

Also, it seems obvious that one end is a smaller diameter.  Should you decide to take the plunge, it should be easy to tell which end to hit.

That thing is a monument to industrial manufacturing of a bygone era. Obviously neglected, 122 years old and still quite a viable sewing machine.  I'm going to go oil something ...

True. They show up pretty well with the macro camera lens, or through a jeweler's loupe.

A tiny bit of progress..
