Adjustable B' vent?

[Vern Heiler]

I know the tape is wrong, but don't know if this is adjustable b'vent or not. Doesn't look right to me. Anybody recognize it?

Depends on how the connection was made under the tape?

I agree. The tab I can see doesn't look like the clamps I have seen before. I'm going to leave it as a possible repair item for the plumber who removes the tape.
