Value is highly dependent on condition, and the pearl handles or engraving may or may not affect the value. In "very good condition", a Meriden revolver is worth about $400. But it "good" condition, it is down to $150. $75 for "fair" and $50 for "poor"
it sounds like you have a DA revolver with a hand ejector that is the cylinder rolls out to the left. The value is round 400.00. The barrel I assume is 6 inches.
