Marc may well be right- there is a faint line in line with the M on both barrels in that area- might be fotoflash- but it looks like the reblued barrels in the breech area have a different "sheen?" nice older Parker but some of the marks on the receiver near the engraved ovals seem strange- not being a photographer, I'll leave it at that-

Nancy, if your magnifier inspection proves the latest revelation correct, your gun has been sleeved with fluid steel tubes, probably by a skilled craftsman, and will probably have excellent bores. See if you can find any markings that may give a clue to the identity of the person who did the work. If no European proof marks, it was probably done in this country, maybe by Frank Lefever and Son in New York, not a bad sleever in most cases. The nearly invisible seam resembles his work.
