Looking for a glass ID on this piece from the 90s to early 2000s out of Socal

Any information would be greatly appreciated! My coworker who gave it to me said something about it being made by the gathering piece? Also the downstream and slide are not stock!

There are so many different people blowing similar pieces. Super hard to identify

Can't help you but it is a super cool piece! Take care of it.
