Guess the thing? #procterphd pen still wrong

@adamprocter Looks like some sort of slide projector?

@smokey yes indeed thanks 😀

@adamprocter I’ve mostly only ever seen/used the carousel versions, but I do remember once or twice having seen the “slide boxes” for that version (as well as something else more like a filmstrip, or at least perpendicular to the lens). The “box” is a pretty distinguishing feature in your drawing, as well as that area around the lens. Good times, those lovely old beasts :-)
