I believe that is a Babbit Chain.

If you really want to retrace the footsteps ...
Yes, I'll agree, Babbitt chain. It was often marked in feet, and tenths. No hundredths.?ÿ
There is a whole genre of action associated with that gear. I was especially amused at the add on edm mounts, on the transit, and the addition to the box, to carry it all. Ah! The memories!
Just looking at it makes me so tired, that maybe I just quit surveying!
