I’m not sure why gunports on a weather deck had lids in the first place. Most don’t. If it rains, the guns get wet. The deck is high enough above the waterline that sea water coming in isn’t a problem. Why bother with gun port lids?
that is a good point and from what I can find war ships on the Great Lakes did not have gun port lids
the Niagara did not

the Jefferson did not

nor did the eagle
but that does not mean ALL ships did not have gunports take a look at the wreck of the Ontario

if the Ontario did not have gun port lids there would be a black opening like the stern windows, but the area where the gun port is, is covered with Zebra mussels so they must be on the surface of the lid. It is difficult to tell but the lid surface looks smooth and no sigh of a little door, you would think there would be some sort of shadow or bump if there was a little door in the lid. remember this ship was build in a wilderness shipyard where iron was hard to come by so I don't think there was a little door, just because of the iron work for the hinges.
