Vintage Compression Driver Identity Unknown

[altecman]

Just picked up a single compression driver and for the life of me can't identify it. I've looked all over it and found no markings at all. Wondering if someone could help me identify it?

Doing a little web surfing and saw these, no info though. I see there were Type S.U 10 & 12 versions of this model. Does anyone know if these drivers were any good or comparable to the Vitavox GP-1.

Hmmm. Not familiar with those at all.

How about a picture of the diaphragm? It'd be interesting to know if they used one that is common to other drivers.

............... and whether it's phenolic or aluminum.

Vitavox bought a lot of license, they may well incorporate design features that are native to this country(read WE/RCA).

Didn't really want to pull them apart till I know how they are constructed, found the patent for them though.
