Good people at Corning Glass but I disagree with that date !! My opinion would be mid 1930`s through the 40` !! The decanter above is decorated similarly just a different form !! They are giving a possible date of mid century 1950 or 60`s !! Finding the maker would be like finding that needle in the haystack !! Very few were ever marked in any way !! Czech Bohemian is a possibility although these are minimally decorated and many from that area were heavily decorated !! Wish I could help but sometimes it is difficult to even guess !!
