KC342
·Purchased my first vintage constellation pie pan all stainless with caliber 564 ref 168.005. To me this piece looked original and correct. However once seeing the movement I saw the last 4 digits of serial number to be what looks like drilled out!! I have never seen this and was wondering if anyone else has. Did not know if this was common practice if maybe the bridge was replaced or movement swapped out from a donor? Any thoughts or comments are appreciated. Thanks
