You mentioned the PO experienced smoking after rebuild. By the look of the piston dome I'm not surprised. That's a LOT of built up burnt oil. The piston skirt is spotless, I don't see any scratches on it. Something caused oil to pour into the cylinder and the top end was starved of oil. The cylinder looks good too. I would get the piston bead blasted or use a brass wire brush to scrape off the goo. Then slip the piston down the bore and take some measurements, ring end gap too. I know you bought a bunch of new parts. If you have time let us know how the old parts measured up.
