AND it says 40-6 on the box in your first post.
You know, I've read that 40-6 probably 30 times or more, and in my mind I read it as years... not gear ratio.
Now that you mention it being the gear ratio; I just realized the years mentioned on the box are 1939-40.
This is why I have been trying to find someone with one of their catalogs. There is an ebay seller peddling a photocopy version, but I just don't want to spend $30 plus postage for a copy...$$$
