A stunning piece of vintage industrial history and nostalgia. 
I have had these before, however this is a particularly nice one, I don’t believe I have ever had a triple one before. A couple of the numbers are missing and have been filled in manually, many moons ago, though that doesn’t make it any less decorative. 
This one is numbered 76 - 150
There are a couple of losses, which I have shown in the photographs. Again this doesn’t distract from its appearance. 
 
This lovely piece would have been hung on the wall beside a clocking in/out machine in a work place, possibly a factory or a shop.
 
This one is particularly nice having the wooden frame around the slots and two rows of slots.
