My New Hahl Clock

I just picked up this Hahl Pneumatic Master Clock. Not sure of the year, but it probably dates to around 1910 or so. This clock is unrestored but complete. Some models had two pneumatic plungers, but this one has only one. It was obviously built to power fewer clocks than the two plunger models.

The clock has the original programmable bell dial with it. It also has the original relays and buttons for the four bells that it rang.

This looks like it will be a fun project!!!
