That saddle. Ouch.
Doesn't seem like it'd be that big of a project to get the thing back to 1972 spec. The cost of certain replacements such as the vintage tubular tires would be prohibitive, though you'd get more for it in a flip if it were period-correct.
Whoever buys the bike is in for a treat. The ride is superb on the pre-73 PX-10s. And if you don't like the tubies currently mounted, you can replace those with Conti sprint 25s for additional comfort.
