I'm looking into this for an elderly neighbor of my mothers, it was his sons bike and the son passed away and he's interested in getting rid of the bike.

I've already ruled myself out because he has some ideas of it's value but with the repaint and non-original components I just don't know what to tell him.

I's 99% sure it's a PX-10 but the son had it repainted soon after buying it new, his two brothers also bought similar bikes and one of the others painted his as well but apparently the third is in original paint.

This one has had a lot of components switched out and it looks like he bought good stuff, the original wheels are still with the bike and included in the last shot, they're tubulars on unknown rims with Normandy hubs. Apparently the rest of the original bits are long gone.

Here it is,
