I'm not in the mood to do it for you, but I think you'll find the answer to your question here:

Thanks for the answer!
According to https://www.torpedo-coasterbrake.com/hub-date.htm “On hubs made from 1975 to 1989, you will find 2 letters on the brake lever. The one above is for the month.”

On my brake lever the letter above (for the month) is U. How to translate it to a certain month, since U is the 21st letter (or 19th excluding J and Q)?

I have a similar hub on a bike I've been unable to date....this should help.

That reminds me of my brother. He's a computer programmer and everyone always calls him for computer help. I asked him one day how he knows so much about computers. His reply was "Google"

As a recent holder of a M.Sc. degree in Computer Engineering, I can confirm that this is what we do. We have been trying to keep it as a secret from society all this years but since your brother broke the code, I can speak as well.

We just look at Google.

...but the trick is knowing what to Google and how to edit search syntax to find the obscure stuff you're looking for!
