Hartal habitation door lock mechanism for Rapido 9048DF

[LittleGreyCat]

At the moment I am struggling to source a Hartal internal mechanism for the habitation door.
It has the common fault - the pin has broken off.
The Hartal importer to the UK only imports UK variants, not for Continental motor homes.
I can find many posts about this common problem, but so far haven't found one which gives details of a supplier for the parts.

Many people have fixed the mechanism by replacing the broken pin, however the MH is on the drive, it is raining and I am not confident about closing and locking the door with the mechanism out.

Has anyone sourced the Continental variant (part number ending PEZ)?
If so, from where, please, and for how much?

Broadening the question:
Hartal are a generic supplier to caravans and motor homes, so it is quite possible that the same part is found in different brands of motor home.
Attached is a picture of the Rapido habitation door lock.
Does this look familiar from another manufacturer?
