vintage 1970s popcorn maker (The Nurserylands TW12)

This was rescued from an elderly friend's bags I was going to take to recycling! so forgive it's condition and if anyone does want it they will need to give it a good clean ... but i can't just chuck it without offering it to any interested party. the thingey inside turns happily ... at the moment it's soaking in bio washing powder ... but it will need further passion and gusto thrown into the cleaning of what is probably built-up gas grease and sugar (?).
