Re: Colt 1908 Vest Pocket .25 ACP
Per Flayderman's Guide, "Blued finish was standard; fair number in nickel plating." Value is listed at $250 for very good, $500 for excellent. That would be for the standard blued model - nickel value not listed, but undoubtedly higher.
There is no mention of pearl grips - just either hard rubber or checkered walnut, both with COLT markings. I don't think the grips are original. Notice their fit and the teltale markings probably left by slightly larger, original grips. Remove the grips and post photos of the frame. Not sure what non-original grips, even if pearl, would do to the value. For me, it would reduce what the value would be otherwise.
Production ended with serial no. 409061, so this one is very late.
