1988 Sundancer 25 missing entry door lock

[Amfiska]

Hi everyone,
We are new owners of a beautiful classic Searay sundancer 25, 1988. The cabin has a folding door but it's missing the lock center part (left with a hole). Being in United Kingdom with an American classic boat, finding out part numbers/any parts is like seeing Santa on Christmas eve, an impossible task.
So please can anyone advise what lock brand is it, how to find it, or even what else could it be replaced with? and thank you in advance...
I will upload a pic of how it is, and one we found off Internet of what it looks like (no brand known still).

TaylorMade made many of our parts for doors and hatches. I MIGHT be able to help. Please PM me tomorrow afternoon late. I might have a answer for you then

In your third picture, that looks like a standard Perko flush mount latch. Try Googling for that and see if I guessed right!

Please take some better pictures from both sides of the mechanism.

Yes you're right, the pictures aren't great..I will add better ones in a few days time when we have another chance to get to the boat. Its been raining non stop this week. Awful weather in the UK, don't recomend it
