Mostly! Except for the top greeblie
taken from my oxygen tank RPF thread this year, this is a mold of the Millenium falcon oxygen tanks they wore in the “caveâ€
Bottom greeblie on these is unidentified.
Top/side are from a Sparklets and BOC soda syphon, bottom is an aircraft reducing valve (I found one) and the top looks like some plastic switch button but idk what that is!
There are two tank model kit parts (90% sure) plugging the side holes
