I dunno Willie, bear in mind '75 was the last year of production for the 58TC, and I know they elminated the bulkhead behind the pilothouse and enclosed the upper salon on the later models. Maybe that railing between the galley and salon is factory, maybe not. I've never been on a later model TC, but I've seen other owners make such modifications and will probably follow suit one day.
As for the ladder, mine doesn't fold either, does yours? That ladder is in the original location (unlike mine), but I'm thinking somebody reversed it to pick up a little more space in the salon. Those are 871T's, so I doubt they'd be much slower than our 12N's.
Looks like somebody may have gotten a little happy with the varnish in some areas, but for the money, she looks pretty dang good. Maybe a touch of red velvet would seal the deal.
