M-37 mirrors?

Did the M-37s originally come with both the small round mirror and the larger rectangular mirror? If so when did they switch over?

Originally, only the small round flat mirror, only on the drivers side..

I would do no less than a 5"X7" rectangular mirror with a 5" convex mirror on both left and right sides for driving in today's traffic. We did a pair of west coast mirrors for the Timken Bearing M37 a few years back. It was a custom built duplicate of the 2 1/2 ton M35A2 mirror system only on a smaller scale. It looked great and functionality was SUPER, steady as a rock. You can check out that build on the photo/client pages of our website if you have interest.
