Mystery Horns

[PeteMcK]

Anyone recognise these? I can't find an EIA manufacturers code that matches the numbers on the back, which are 824 0047 109 and 824 0047 947. Found in close proximity to EVM12s.
Front view:

sorry, this is a little bit fuzzy...

Looks a little like an EV T-35 with a square magnet.

Not sure though, others might help

Cal,

The only pics I can find of T-35s have round magnets IIRC,
maybe this is a newer version? Looks like the T-35 from the front.

A T-35B, I believe...

[PeteMcK]

the only pics I can find of a T-35B have a round magnet too;
I'm going on the theory that these are some late version of the T-35, the front of the horn can't be anything else, and the units were crossed over at 3.5Khz, which is what is recommended for the T-35s.

Cheers,
