The baseplates have to have a "cassette lug" to allow use of the Leica
cassette;  the purpose of this is to open the Leica cassette when the
baseplate is closed -- then, there is no light-trap at all, and the film
moves without physical contact of any sort.  Thus, film will NEVER be
scratched with a Leica cassette.

The early M6's (Wetzlar-built) had the cassette lugs in the base-plate.
The later ones do not, but the M4-2 baseplate is available as a
replacement.  The Leica motor drive does have the cassette lug.

I regularly use Leica cassettes on my M3 and M6.

Oh!  And you can drop them, all day long, and they simply cannot pop open
without a REAL blow, such as that administered by a 10-ton machine press.
