Well, I dispute that statement, intensely.  Series filters are quite easy
to get and quite inexpensive:  Harrison & Harrison, for instance, produces
a full range of them, for around $10 each, give or take.  And I believe
both Heliopan and B+W still produce them as well.

As to the Leica conversions, though, these can be found on page 257 of that
indispensable, though incomplete, referrence, Laney's LEICA COLLECTORS GUIDE.

The 2/50 Summicron-R takes a Series VI adapter with an E44 thread.  The
early 2.8/135 Elmarit takes a Series VII adapter with an E54 thread.  In
both cases, Leitz sold polarizers with those threads and did not rely on a
Series polarizer, though one WAS made in Series VII (13370) for the 2.8 and
2/35 R lenses, which did have the rotating wheel.

The E44 polarizer is Leitz 13358 (graduated) or 13353 (circular);  the E54
polarizer is Leitz 13359 (graduated) or 13354 (circular).

Please note that I have one of the E54 polarizers available on my FS list.
