torque converter ID

[buickgirl68]

I bought a torque converter off of a guy from the board that said it came from Postons. I called them up with the numbers I have and they said it wasn't one of theirs. So I am wondering if any one knows what this might be
before i install it in my car. Here are the numbers K3 3B 092 and K2 2F 250. with a big 25 stamped on the front.
Thanks
