I was looking at a very early high grade Parker today. In the 4,000 serial number range. There is records to suggest that the gun went back to the factory at a point in its life, but cannot tell what for.
The barrels show evidence of some work possibly being done. Along with some tightening work to the barrel lug.
It has a piece pinned and soldered onto the hook. The solder has since popped free, But the pin still holds the piece in place with a little movement. I know that this type of repair has been seen on some older Parker guns and discussed here before.
However, there is another repair that I found when looking closely that was new to my eyes at least. There is a piece dovetailed and soldered in place at the back of the locking lug. This is the surface that bears against the "bridge" in the water table slot.
