It's not as simple as it looks after the 70's. The 4401 and 4411 came out after their consumer counter parts if the catalogs are complete.

The 096 is not a 4313 wrong tweeter.

The LT3 and Lt series vs 4408-4412 uses the same drivers in some but not all cases and is fixed no L-Pads so different networks as a minimum.

The 6332 would be an L100 Century Gold not sure about crossovers or drivers definite frame changes and tweeter.

In the 70's in many cases they were clones after that it gets blurred. Blurred as in an L212 is related to 4315 but not the same.
