 The PTO side of my old 440 ring broke.  I think this is the first time its been apart.  Is the stock piston stamped STD and CN?  The cylinder looks perfect not a scratch nor does the fan side.  Can I get away with new stock pistons and rings wrist pin and wrist pin bearing along with new gaskets?  Its just a basic easy riding machine for us older guys.  Passed with flying colors a leak down test before I took it apart.

Pictures are decent but never as good as in your hand ,,, the LH pictured piston looks more like a foreign object came in the intake or dropped
the electrode off a spark plug some time in the past.
Or as you mentioned , broke the ring and dropped a piece in a port and drew it back in ,,, cant see any missing ring in picture..
.
you might want to hone first before dropping in the new parts and drive on
