I found one side happened to be true to the block mortise. And the front face was dead on too. 3 deg I think. Using those as references, I thread milled to correct the 3/4 deg down angle on the thread. Took it all the way out to 1-1/16 to clean up.
I have a picture somewhere of a mandrel threaded into the original thread. Clear by eyeball it was way crooked.
The hanger was cut off prior, and replaced with barrel mounted lugs.
I missed on my guess of where centerline was in relation to the lever pin by a little. So the primers are hit a little off center.
