my neighbour gave me this today for mowing their lawn,
it's not 100% there's a latch or something that is not engaging because when you slide it over, it just moves back to the left without typing, either way I still think its cool even if all it ever does is decorate my shelf :P
just from wikipedia I believe it's from the early 60's, but i'm not 100% sure if anyone knows anything about things feel free to let me know.
