Manufacture dates for Royal

[vintagevac]

Good evening all. This is my first post and I am hoping someone can help. I have a couple photos of Royals and looking for possible dates of manufacture. Hopefully I'll do this right.

The first nameplate you show us is from a model 801, dated November 1971. Until 1985, the letter "I" was not used (skipping from "H" to "J" for the month of September, to avoid confusion with the number "1"), hence why "L" in the first case means November.


 


The second nameplate you show us is from a model 606 from around 1969 or 1970, before the date code was adopted.


 


And the third nameplate you show us is from a model 880, dated March 1980.
