What is this object?

Can anyone identify this piece of equipment? Made by Stanley.

I think it's for cutting boards at an angle.

yes, a miter saw.  A hand saw would be inserted in the two vertical guides and adjusted to the right or left to set the angle.  

Here is a modern one:

Although most people use this except for fine cabinet work:

MMMMMMMMMMMMMMM! A 10" dual-bevel sliding compound miter saw. With positive stops on the miter wheel. And a laser guide? 

Wait, I gotta go take a cold shower.

 Well, some of us hate Dewalts, and our cabinets come out just fine.  Bosch and Makita are my choices.

 I dropped my beloved Hitachi compound miter saw on a cold day a couple years back. I watch the plastic handle shatter in horror and disbelief. 

I replaced it with a DeWalt, but didn't get the laser guide. I sometimes regret that decision.

Thanks everyone. Would anyone like to own this fine piece of equipment? It’s looking for a new home. Cleaned up a little, it would look great on a mantle. 

I wonder when it’s from? My house was built in 1857 and has lots of fancy exterior woodwork. I believe that’s about when the technology became available to feasibly produce trim on that scale. Could it be from that era?
