Altas Mill Type Question

[BIGPAULY]

I picked up an Atlas MFB a while back for a restoration project. The main casing has a p/n fix to the mold to print M1-1A. The mill has most of the parts to make it an MFC type. Has anyone seen this before?

The parts to convert to the MFC arbor support, yes. The gear guard and cover and couple of other parts, not so much.
