Hi,
I recently bought an old door lock at a thrift shop. I dont know what kind it is, but its definitly old. I took some pictures of it.
This is the lock with the key next to it: http://imageshack.us/f/9/lsognkkel.jpg/

And these pictures are of the key being turned. Notice the grey square. Thats attached to the locking bolt. When the key is turned, the yellow(-ish) discs are lifted until there is room for the grey square to move, then its pushed one notch forward:

That was a lot of pictures, but I hope it means someone can identify it. I would love to find out some more about it!
