The exterior angles make it look like a modification, not an integral design. The interior finish (and lack of it in some places) also make it seem to be a later modification, not a factory production.
I suspect that it's a early 90's 42 sport sedan that has had the flybridge removed and has been modified for a reverse rack wind shied. the current model of 42 is marked as a 46.
So I found out that this was a 1987 OA 42 sedan that had a galley fire in the early 90’s. This is the result, a custom bridge and galley. Also, after seeing it, going through it, and running it at sea, I would say it is done pretty well.
