Can't seem to find the part number and/or associated set number(s)?

 

Here is the piece, and here is a list of all the sets that have this piece.

 

Hope this helps.

It looks like the type of space helmet that allows the Alien creature to go inside your glass and go down your throat and then we all know what happens after a good dinner.

this is from a diver, came with black fins, blue legs, black/white/blue torso, that theme with the octopi,  aquanauts is the theme name I think.

Old school aquazone! Second favorite theme after LEGO space :P
