yes, mike, i have one.
i found it at the local yard sale and bought it even though it was not something i needed. it is in its original box and i have not looked at the actual vent.
unfortunately, somebody opened the box years ago and let in the dust.
it is totally black with dust. you may have it, send me your address and i will package it so it should not break in transit.
you may even have the dust!!! isn't that a deal???
