I finally got a buttstock attachment assembly from Damon in hand at the same time as a colt.

The colt one is on the right.
Both of these are very very close. Overall length, width, distance from the screw or bolts holes all the same. There is the slightest of differences on the slot where the frame slides in. It is cut .02 inches higher on Damon’s than on the colt, and its .02 inches wider inside. All other measurements are the same. I checked the fit of both on a original colt stock and they both fit the same.
Wanted to add this to the font of knowledge floating around out there.
Nice work Damon.
