I'm going to agree with Goose on this one. I'm pretty sure it's a NP202, but for some special industrial application. Look at the rear output, it appears to be light duty as compared to the front output, which with that rear cover, is much heavier duty than standard 202/205.
My guess is it's from a forklift or somesuch that used the rear output to drive a PTO or something, and the front output was for locomotion. That rear cover on the front output has to be for a tapered roller bearing, as opposed to the (relatively) light duty caged needle bearing cover of a 205.
