Thanks for the kind words, JW. You have a lot to be proud of!
You have a .32 Hand Ejector from the early 1920's. I can't get you any closer than that so someone will be along that tracks these and can be more precise. It chambers both .32 S&W and .32 S&W Long. The pearl grips are aftermarket and add some value over the original black hard rubber grips like these:
These guns are nice shooters due to being very easy on the recoil. However, they aren't very valuable unless they are close to perfect condition. My guestimate is $200-300.
