What are they?
I think they were once painted white. The hole in the 2nd one appears to have been a "after market" custom addition.
I see the company made smokers.
Thanks!

They look like covers. I see there's a mounting hole on the bottom. Possibly used to cover the gear on an extractor.

I think that they were gear covers for woodman extractors
