I've never seen one exactly like it, but I've seen an old "starter pistol" that was very similar. They are intended for use with blanks only, and are used to start races, such as in track meets.

A clue would be whether the barrel is rifled or not.... if it's a smoothbore, I'd give it a 99% chance of being a starter pistol.

Solowsonoma,
I have a cap pistol that is very similar the pistol you have.
My old eyes arn't so good, but when I enlarge your picture, the cylinder looks like it is part of the frame and does not rotate.
The one I have, the barrel is fixed and does not tip down. There is an "S" on the left side of the frame and a "W" on the right side of the frame. It is approximately 5-1/2" long.
A few photos to compare.

Okay, please take a look through the barrel.

Is it clear all the way through?

Is it rifled?

From what I can see it is a cap pistol from the 1930's-1940's.......but that is just me!!!
