Showing the pinholes of the CD 202 K's. The top of the right hand one is messed up (some kind of molding anomaly) so it does not show a clear "dot". The left one shows hints of an Elmer ring, but it appears that the top of the plunger used to mold this one had some surface damage, so the ring is obscured somewhat. Not so obvious is the thread profile, again sharp threads on the right.
