hello Banden - welcome to the GMB.
Regret I can't help you with an answer to your question as to why these are engraved with this particular word - but would suggest these are custard cups from the early years of the C20.
Custard cups were very common during this period you mention (and of course go back a lot further), and continued for later than this probably - cut olives of some description being a common form of decoration on custard cups. I have at least one with identically cut olives.
If we learn nothing else in life, it is that glass travels, and much Continental/Scandinavian material is found in the U.K., and doubtless vice versa.
You don't mention the size (height) - which is always useful - but I'd suggest they are something like 80 mm (about 3.25") tall.
Hopefully, someone may have the answer as to their origin - fingers crossed.
