Looking to sell/identify a lamp

[Jagger Robert Brammer]

Hi, picked this lamp up on marketplace and was wondering what it is/how much it's worth. Looks to be a 16/17 inch vintage model, but not sure.

Hi, we meet again, I have some knowledge of lava lamps so hope this helps. You have a large neon green lava lamp made by the original lava brand. (Possibility yours was sold at Spencer's) They usually go around for 150-250.
