A decent mid range Hohner Carena IIIM piano accordion, full size, with the lovely Hohner sound. I refurbished the bass end (clean up, revalve, rewax, tune) after which it sounded marvellous, with a deep honking bass when all five reed sets were called into service. On the right hand it is a three voice instrument (LMM), with five registers to mix and match the sound. I sorted out the various issues with loose valves and reeds and tuned up. The buyer wanted me to service their eBay acquired PA but when I showed them this instrument they changed their minds. That is the problem with buying accordions from eBay. You are never quite sure what you going to get unless it is supplied by an instrument vendor or repairer.
And here is a video of the restored PA:
