Dick:
A couple of guesses:
1. Too high a viscosity oil. When cold it turns to molasses, and
it is very slow to register pressure.
Might be because the owner worried about low oil pressure when
hot at idle?
2. Lack of an anti drain back valve in the filter. This does not
seem likely, but since I do not
run a spin on conversion, I thought I would mention it. In my
Pontiac Fiero of years gone by,
installing a filter with no drain back valve would cause a
nasty rattle on start up and a long
delay before oil pressure registered.
3. Both of the above?

Subject: Oil filter pressure question
List---While on this subject, a TR6 came my way a few weeks ago that
seemed to take too much time before the oil gauge showed any pressure
after the engine started, when cold. My OE filter shows pressure at the
gauge within three seconds from cold. It had the spin-on conversion,
which should be faster, but this one sure wasn't
Any ideas here?
