Hi , you didn't say which screws are rusted . However if the locks are out of the gun you could carefully heat the screw with a small oxyacetylene flame . If this is not possible , soak them in penetrating oil for a few days . Sometimes a nut can be welded on the head of a screw to allow a spanner to be used. A good way to break corrosion bond is to soak the part in a mixture of lemon juice and vinegar . Get an experienced welder to do any heating or welding . Good luck .

Hi , I clean and lubricate the flintlocks after every shooting session. The percussion locks , about every third time , [ they don't get so dirty ] . By and large , Pedersoli locks are well made , however I am experiencing a problem with the Mortimer and am looking into a way of resolving the dilemma . Will let you know when that happens .

I heard, Dixie Gun Works has a gunsmith who repairs Pedersoli locks, in case you can't resolve the problem yourself.
