A family Parker

[Dennis]

Patrick,
I can tell you that when I received one of my Parkers I turned the trigger guard so I could check the serial number underneath the trigger guard tang. Mine turned easily but there was only one hole. If I can say this properly, the trigger guard is the screw head and you simply need to turn the trigger guard. Obviously easier said than done if yours is rusted tight. I would put some more oil in there and let it set for another day or so. Then if it doesn't unscrew by finger pressure I would gently and I really mean GENTLY use something non marring such as a screw driver handle and put a SMALL amount of pressure on the screw by putting it through the trigger guard. You don't want to bend the guard but sometimes a bit of leverage is just enough to free the rust hold and then will let it unscrew. Good luck with it. Probably others will have better ideas but that is mine.
