That is easy, From what i recall WM has them.
My boat they only swing one way with the way the PO made them. ie out! They also have an overlap so rain for the most part in the middle will not get in, and are low enough that the hatch slides forward, vs having to remove and slightly lower the upper board so the hatch goes forward.
Also, my swing doors are smoke plastic of some sort like the hatch, so they do let more light than the wood boards. This can be good, and bad!
You might also try larger single shop places like Fisheries, Defender, not sure about the sailnet store equal.
not sure if this search at fisheries will work using just hinges, but there are all kinds, some SS, bronze, plated etc.
