Most screw-in polarising filters have a white mark on
the outer ring.  If you note the position of this mark on
the filter you are looking through you can easily move
the filter on the camera to the same angle.  Best to buy
two identical filters if you're going to try this.

There are two in two different shops in my local city.
I don't know where you live - I'm in Cambridge in the
UK.  If you are really having difficulty finding one I
could buy one for you and send it in the mail.

Incidentally, I have two swing-out polarisers that fit
the E39 lenses.  Only one has the built-in lens hood,
and the one that doesn't is slightly smaller in diameter
and vignettes on a 35mm lens.  I assume this is an
older filter - can anybody fill me in on how many
different types of swing-out pols there are?

You mention "clip-on".  Both of mine have a small screw
that you tighten to hold the filter on the lens.  Is this what
you mean, or is there another filter which clips on like
the lens hoods for the last generation 35 and 50 Summicrons?
