Help Identifying HF driver

[BHearon]

I have an Altec model 19 with 811B horns. Removing the horn to inspect the driver has me puzzled about what transducer I have. It is labeled with model number that I don't recognize.

What does this mean? Is this an Altec driver or a no name replacement?

That's simply the "unlabelled,,,oem" version of an Altec 802-8G .
