Hot Rods Help with id on bearing shells.

I have a few old special rods with insert bearings. They are 2" inner diameter and the only markings are 2891-010.
Anyone with bearing catalogues who can tell what this is for? Thanks.

 

Another

 

Mcquay Norris brand. I believe these are for the 1940 Ford V8-60 rods (one year only application).

 

I have a 1910 to1935 McQuay-Norris catalog with numerical listings. The highest number for bearings is 2164. SO...... guessing post 1935 ish?

 

I was incorrect on the catalog....its up to 1930
