Marvin, The Germans used a dot to indicate the rework of the holdopen added. This dot can be found on the right side of the frame.Mostly I have seen it on 1908's that did not originally have a hold open and when it was added the dot was placed to indicate it without opening up the pistol.I question why a barrell replacement would require such an indicator. Or any other part replaced for that matter. Serial numbers or the lack of would generally take care of that . Any other minor part would not need an indicator if it was processed thru the system and passed inspection. Jerry
