Wanted: Master Cabin escape hatch

This is a long shot, I know. The original MC escape hatch on my 1973 '53 Classic was removed. The escape hatch is the single deck-mounted one in the center of the aft deck. I have all of the original hardware and trim inside with a blank where the hatch used to be. I need only the external hatch that screws into the deck.

I got rid of that toe buster and put in 2 larger escape size windows in the stern. We anchor a lot and use the aft deck door to get to the swim platform so I don’t miss that thing sticking up, sorry I threw it away.

What size is it. I have one from a 53c 1972. Don't know if they match.
