My bad, auto correct in play! I would be surprised if it were Deere as in John Deere. I saw somewhere it referenced Deere.
Regarding the bearing types, Babbitt is a leaded replaceable bearing usually used for slower moving parts. You will notice in the write up/specs that they reference a replaceable bearing for continuous duty applications. The Staufer is a lubricator, a cap usually filled with grease or lubricant as you turn it.
The style if the casting is rugged and typical for the time primarily because the casting technology was not available to make it thinner.
Hope that helps
