I picked this up at a garage sale a few years ago. I love it.
Anyone know what year it might be?
I'd like to know more about it.

Nice find
Hi, Wallnut. :-)
Looks like the Smithsonian has one:

Here's the newest patent identified with a date on the back of the thermostat:

And here's the one patented by Butz in 1889:

A lot nicer than my dad's crappy one in his 50's house, but not retro like yours !~
D'oh! I did this in too much of a hurry the other day.
Here are the two 1886 Butz patents for damper/flapper regulation:
