Re: Cracks weldable on Pre war frame ?
A welder proficient at TIG welding could repair those cracks easily. Done right, the weld will be stronger than the surrounding metal.
My concern would be the inside diameter. If I'm seeing it correctly that's exactly where the inner bearing race will need to fit. That I.D (inside diameter) will need to be precise for a good fit.
Good luck and let us know where you go from here.
