I've looked at Echohawk's complete list of monster's in D&D. According to that, the "stained glass golem" is only in the 3.0 Monster Manual II (and it's 3.5 update booklet).
There are some other instances of a "glass golem" in 2E, but only in sourcebooks, not adventures. However, this is because Echohawk's list only shows where a complete monster entry is found - since the glass golem was in the 2E Monstrous Manual, it could have been featured in an adventure and it wouldn't be noted on that list.
