ב''ה,

The regulations haven't changed much, although I guess SSB (as can somewhat improve range per watt at the expense of compatibility) is allowed slightly more output power legally.

So, in working order, this is probably about as good as any CB set ever, and for contacting the widest range of them.

It's fun, as is proper ham stuff. Since trucking exists and some emergency services might still even monitor channel 9 somewhere (maybe there was a rare amount of local variation with that?), could still be useful if needed.
