Well, SLM has it down pretty well, though I don't believe these drivers were produced into the 70's. I doubt even into the 60's.The model numbers are confusing, but the basic differences have been pointed out- the phasing plug slits vs. the holes.
There is also a difference in diaphrams, which Bill Woods has measured (along with the slits vs. holes- again, thanks to Bill aka RCA Fan.) The diaphrams with sawtooth formers are different from the straigtht paper former.
Otherwise, you should be able to have some fun. If I remember correctly, you have the wide dispersion horn meant to shoot the sound across the bottom tier seats of the theater. The horns came with a corresponding narrower, higher horn that when mounted with a dual throat would hit the mezzanine. You may encounter some issues with the wide dispersion. In that case, Bill is making a conical horn specifically for this driver, as it is probably the ultimate sleeper compression driver out there.
Good Luck,
Jonathan
