vintage green glass water goblets or large wine glasses, moss olive avocado green

We love the weight and retro shape of these nice large water or wine glasses, but we don't know the pattern name or maker. Replacements dot com calls them unknown, UNK839 (g - green).

We're guessing the age at late 60s or 1970s based on the retro color - moss green, olive green, avocado green, whatever you'd call it.

They're about 5 1/4" tall, and the whole set of four is in excellent condition without damage or wear.
