Looks like a nice project unit.
My Meck Philharmonic Model 8200 was in very similar condition (except on mine the veneer was still in good shape yet) mine unfortunately didn't have its original back cover intact anymore.
But I'm not sure if it ever had one to begin with because the TV didn't have a safety interlock plug and also there's no signs of any screw holes on the back of the cabinet where there would of been a back cover attached at one time.
