Hello Joel,
IF there's a finger hole on the underside of the brass-colored knob, the lid only is a cover for a Wagner round roaster.
I don't believe the oven is a Wagner due to the wire bail handle and the marking on the underside of the assist tab. That said I would guess the oven is a Lodge... also the oven's bottom markings appear to be Lodge.
In other words, you probably have a marriage. No sin there... will still be a great user if the cover is a good fit.
Hope this helps.
