WTB 45 Degree Viewfinder

I'm interested in a 45 degree viewfinder for a Sea & Sea MDX housing (specifically the mdx850). It could be the official Sea & Sea VF45 or an Inon Viewfinder Unit II for Inon X-2 housings (I have an adapter).

Have an Inon 45 deg that is adaptable to S&S, pretty sure I have that S&S part also but has Nauticam adapter adapter at moment, easy change out. PM me if interested.

I am no longer looking for a viewfinder, I purchased one from Eyematey.
