What caused the loss of oil pressure?

I have no experience of rotaries other than stripping a well used 1988 turbo
model. The oil had been drained before I bought it bu what struck me was how
clean the remaining oil was and everything else in the engine, there was no
sign of gunge I have always found in a piston engine

Stupidity and impatience. I didn't dare run the starter long enough to get oil
pressure showing and figured "it'll come up when the engine starts running".
Possibly a bad oil pump also (although not fully verified, it seemed to work
intermittently when turned by an electric drill - which doesn't make sense, so I
put in a new one).

As I mentioned, after changing oil, I had to run the starter 2 - 3 minutes (in 60
sec intervals) before I got oil pressure showing.

I think he means the first time Finn. The time the engine seized.
I think I have your old message on the CD somewhere.

Yes and that was what my answer referred to.
