In Y2K7, there was a thread with a lot of Century projector info. I was unable to find the original thread, but I had saved some of the info on it in my "Century Projector" file on my computerthingy. Below is a copy of what I've got.
Sorry I can't give direct credit to whoever originally compiled the info:
"DECODING CENTURY MODEL NUMBERS"
"M" always means direct drive. "W" always means water cooling "D" means drive in machine (2 shutter blades) "SA" is the basic machine ("DA" the drive in model)
R3 is the basic soundhead model MR3 is the drive model
Century nomenclature:
Base projector models: A, C, H, J
Variations of the "A" model: S=Single shutter D=Double shutter W=Water-cooled aperture TA=turret and aperture changer
Double shutters are denoted in the C, H, and J models by double letters (e..g., CC, HH, JJ). No special designation for water-cooling (although, I have seen a handful marked, "CCW").
Reproducers (R=reproducer), most-common base models: 3,4,5 R3=foward scan R4=reverse scan (many were converted to fwd scan in the field, as Sam said) R5=forward scan, paired with JJ projector T=transistorized M=Direct Drive
"E" was FET (I'm pretty sure), B = Blower (Cinefocus) and the R50 was paired with the JJ not the R5. I've also seen an R20 paired with a JJ in a Standard-Drive configuration.

Yeah, Century screwed up with the naming. Traditional Century was that the letter denoted the model...if the letter was doubled, that denoted double-shutter. Hence CC, HH and JJ are all double shutters.
The "modern" 35mm projector should have gone by "A" and "AA" but alas those names were taken a few times over...so the SA and DA came into being. In theory, adding an "M" to a name makes it direct drive. So an MSA is a direct-drive single shutter "A". But note that a JJ never got an M prefix for being a direct drive (which most, but not all, were). However, the JJ did get the silly name of JJ2-S (or JJ3-S for Cinefocus) for single shutter. It should have just been called the J2 and would have meant the same thing.
Strong ended the line calling the "MSA" the MSC...direct drive, single shutter, "C" but not the vintage "C" Heaven knows why it needed the model change...it was identical to the A but missing parts...like the shutter adjustment, fire shutter...etc.
