I have once again managed to get hold of some vintage gear.
I have two Horn drivers.
One is a Gaumont Kalee 379 driver (made by B.A.F) Golden coloured with a handle
The other is a Rank 379 driver ( grey peppercoat coloured)
Both drivers look very similar, and i believe they were used on the same dual throat horn.
Are these drivers rare to come across?
and are they field coil/ or compression drivers?
Possibly thinking of putting these on the marketplace.
any info is much appreciated.
