Mi-co parking meter

Here's another parking meter I picked up. It's a Mi-co parking meter by Hancook industries in Jackson Michigan. I'm lead to believe its from the 50's but I'm not positive about that, possibly later? It's apparently a pretty rare meter. its currently not working , I don't have the top key for it and the bottom lock is drilled out as you can see, but as soon as I get it open I'll see what's up with it. Overall its in pretty good shape. I just love the look of it.
