Etched Footed Crystal Coupe-Form Glasses: Kosta Boda?

Please let me know if you recognize these glasses.  Initially I thought they were Kosta Boda, but I have not found a match to confirm that.
They are unsigned and unstickered/labeled, but finely made crystal with a wonderful ring and clarity.

Glasses can be really tricky to identify, there are just so many designs to choose from. Other than trawling through replacements dot com (almost a lifetimes work in itself) I would not know where else to start.

Oh yes, trawling the photos at replacements.com - truly a lifetime of work! Thanks, tho, for checking out my post and photos. I also looked at your post of the little, maybe Polish, dish. Another mystery too. Pottery and ceramic makers and their illegible and hard to verify/identify markings. Oh la la!

Susi, you have indirectly helped in the identification of that little Polish dish, Redware must have seen your comment and after having a look has been able to provide some information.

Thanks!
