Tube Help Please

Does anyone recognize this tube?  It is obviously a 2492.  I found a pair in plain white boxes.  I have bought so many 6922 variants and it has no label.  Thanks in advance -

Looks like a Brimar.( KB/AD) Yes, it's a 6922 variant, but have no idea what it brings to the table vs a 6922.

Thank you.  Quick check looks like they were Brimar / Ediswan and I was buying the Ediswan variants at one time.
