Identify "CLS" mark on set of 24 goblets

[Marilyn2020]

"CLS" is very clear, as is Sterling 925. The hallmark appears to be a "4" or "A", and the town/city "Hesboten"?
Need help to date and where made. Many thanks.

Words read "Hecho en Mexico" for Made in Mexico. There is no town designated here. The center mark is a Type 2 Eagle assigned the number "141" prior to this system's demise circa 1979...it is explained at the header right here: https://www.925-1000.com/mexican_marks.html

No maker "CLS" for Mexico came up in a thread search, so we are left without an answer at this junction.

One online listing of maker with similar style CLS, was using next system mark of "ML - 03" which could be an imcomplete stamp of "MC - 03" for Mexico City. Perhaps he can be further traced with that.

CLS has been known to use (Type 2) Eagle "1" and has a prolific output of hollowares, many described as modernist. "ML - 03" appears to be correct (forget what I wrote), so "L" would seem to be the last name for this Mexico City maker or shop. What "S" then represents is unknown.
