I have a question that relates mainly to my morale.
I call this chord shape the "Rev. Gary Davis" C7 because that's the context in which I've been taught it, by a variety of instructors. It was used a lot by RGD, and seemingly it comes up whenever someone wants to teach me a RGD song.
It's a moveable chord involving all six strings -- that is, all six strings are fretted. There is no barre. The chord is 332313. It's formed by first using your four fingers to form a common C7 shape, with index and middle fingers used on the 2nd and 4th strings like an Am7, ring finger on the 3rd string 3rd fret, and pinky on the 1st string 3rd fret. That's not an uncommon C7 at all. But then, one wraps one's thumb around from the top, and catches the 6th
and 5th strings in the third fret.
You can see Stefan Grossman doing it up the neck around the 0:18 mark of this video:

If you're familiar with this fingering and use it from time to time, I'm hoping you can tell me whether it seemed like your hand just wasn't big enough when you started trying it, and what changed, and how you changed it.
I mean, once upon a time I couldn't make barre chords, or couldn't wrap my thumb around to catch an F in an F chord or the F# in a D/F#; and now I can, if clumsily. So on that basis, one might think that if I kept at this, eventually I'd get it. After all, other people have. But it seems *so hard* to wrap that thumb around, given that I'm doing so in the 3rd fret rather than the 1st (as in the case of the F), let alone catching two strings. I'd love to compare my left hand size/finger lengths to folks who make this chord, to find someone with a smaller hand/shorter fingers than I have who does it; that would be encouraging. Given that that's not so feasible online, I wonder if your hand/fingers seemed too small too when you started with this fingering. Is this really going to come if I keep at it?
