shoot-n,
I saw how & where the parts are being made. It's all made right there in CT in one of the old Stanley Tool Co. buildings.

The frames are machined from 4140 forgings, the barrels from barstock of the same steel, the wood is machined in house by a multispindle cnc controlled machine.

The parts are so precisely machined, no hand fitting is done. No gaps either. Even the barrels are machined on face to fit the frame.
