Brilliant! Thank you so much Canvasback.
So now, unfortunately for my wife, I actually am interested in the gun. I figured out what most of the proof marks mean and that the barrels were sleeved sometime relatively recently (1985 - 1997 according the to LC1 crossed sword stamp.
I still have no idea what the 13/1 marks mean.
Anyhow... any idea how hard it would be to find or make a spring? Of course there could be other issues once inside the gun, but the fact that it was sleeved so recently makes me thing it shouldn't be just a total basket case.
Any idea of value?
