Collectors are not fussy, usually.
Anal, yes. Fussy, no.

FYI-
S&W terminology:
"Cylinder Stop" = the little half round thingy in the bottom of the frame that clicks into the notches on the cylinder, and/or makes the turn ring.

"Bolt" = the thingy that helps you open the gun when you push the thumb latch. Open the cyl, and you can see the end of it in the center of the recoil shield.

Colt terms differ, as I recall, but who would expect Colt to know anything?
