Looking at the design,, I am guessing the sailing ship was done in factory,, the C is really bad with llnes that are not smooth and straight !! Evidently it was a later addition from someone after the glasses were purchased !! I am assuming these are bar glasses !! Anything put on the side would be decorative and not likely a factory mark !! The factory marks are usually on the bottom !!
Nothing comes up anywhere with the C and sailing ship logo !!
For some reason, I can only attach one photo. There are three glasses. The one shown is a translucent aquamarine. The other two are dark blue and dark purple.
