As the title of the thread suggests, I'm looking for help to date code my generator. It has a Bosch Reman sticker on it so I doubt that it's close to correct. That said, I'd still like to be able to date it then hopefully find a correct one, suitable for my build date.

I already know that parts are stamped with a 2 or 3-digit sequence.
From 1920-1963, the format was 1 or 2 numeric digits, then an alpha character.
The first 1 or 2 digits are the month, 1 through 12.
The last digit, a letter, is the year.

For 1964-1969, Bosch used a 3-digit numbering scheme. The first digit is the last number of the year. The second 2 digits represent the month.
Example: 401 would be January, 1964. "

Mine is stamped 11U which suggests a November build date but I can't decipher the 'U' as it relates to a year.
