Hi Dwight !
Maybe the lack of the small radius, contour on the e-Bay piece stems from the fact that to have removed the serial number from the back, the machine sanding process took off enough metal to loose the radius...and it wasn't added back before the part was refinished...??? Just WAG'ing, of course...
