Vintage Extreme Ghostbusters Trendmasters Proton Pack NON WORKING Retro 90s

Though the majority of this set is complete, it is in NON WORKING ORDER. The batteries inside the toy had long been corroded. I tried to wipe it out and used some brand new batteries on it, but alas, still no light or sounds. The hose is a bit bent, and there are scuff marks and Nicks throughout. There are some missing pieces, as pictured. Kid Sized
