Well, we can't be sure, we can't see the other end after all. Presuming
that Thomas didn't start to remove the snap ring and then stopped
partway, the snap ring is out of its groove in the input shaft! That
is why the fifth gear got screwed up. The synchro sleeve, and likely
hub, along with fifth gear itself, was able to slide back and forth
since the end stopper wasn't held in place by the ring.

Has this tranny been taken apart in the past? Looks like somebody
didn't get the snap ring seated all the way when they put fifth gear
back together. Looks like the input shaft has wear from the clip
being shoved up.

I'll wager that it was simply a re-assembly screw-up in the past,
no big mystery. No other explanation really for the snap ring being
out of the groove.

Remove that snap ring for real, pull off the synchro sleeve, check
all the teeth of all 5th gear components for wear. Yes, likely you
will have to replace the 5th input gear, synchro sleeve & hub, & baulk
ring. With the endplay in the synchro assembly, it was likely chewing
up those gears. Replace the snap ring, its cheap. The stopper looks
fine, but for a nick or two, but it is probably cheap too. And check
the bearing in the case. That snap ring was pushed along the shaft,
into the bearing, where it stopped moving. Engine running, the input
shaft was spinning, scoring the shaft with the ring, which at that
time was pinned between the stopper and the bearing. Depending on
the damage to the input shaft, actually, I'd be suspicious of that
too. It's definitely noticable in the picture.
