Hinge screw question
 

I just recieved a project gun I bought online and I was looking at it and noticed that the slot on the hinge screw is on the right side of the reciever, all the pictures and the other parker I own have the slot on the left. The screw slot is at about four oclock (bothers me) I am wondering if it got flipped. and that if I got it on the other side the slot might be horizontal when tightened Thought Id check before I started loosening whether this is a simple thing or can I cause myself alot of trouble with this experiment Thanks

Just saw a picture of another right hand slot on the hinge bolt so I guess that may not be my problem. Wonder why some are right sloted and some are left

Those that have the slot on the right side are the ones that have been removed (for whatever reason) and reassembled in reverse. 99.999% of new Parkers left the Gun Works with the slot on the left.

Thanks Dean, Is it hard to change it back to the right way?

I've never had reason to attempt it but I've heard that it is not easy and should be done by a competent Parker gunsmith.
