The lockwork is all gold plated. I thought the same as you about the asthetics of the back action...until I saw this one in hand. It is really a beautiful little gun. Its built on their 28ga frame. But its tiny. The width of the frame at the hinge seems barely over an inch from memory.

I don't know if it has intercepting sears, but would imagine it does.

The gun was 5 lbs 14oz and felt slightly forward balanced which made for a easy to shoot gun.
