Binko I like the 100 year old classics too...because I can't afford the newer ones.

Sorry I said anything about your buggered hinge pin screw....most learn from their mistakes when buying these old guns some never admit it.

A while back I got into a Scott Excellentia grade with some hidden issues that I didn't see it first...(but I got it cheap).
Lucky for me with a little cash it will work out and I will have a nice gun with high condition Damascus bores and high condition egraving.
Who knows it might have been worked on by the same jack legg that buggered your hinge pin screw.
