Means it can be anything other than an original 4000 (it would say "4000
router".)

Could be a 4500, a 4700, or the -M variant of either.

Could be a 4700-M too.

Historically, the -M variants' motherboards have been redesigned to be
more flexible than the M-less' while using the same software and
interfaces. Typical differences are more maximum memory (RAM/flash) or
smaller increments. If the configuration is one that's possible only on
the -M, that's what you have. Otherwise, it could be either. You may
also be able to tell based on the manufacturing date or serial #. How
much that matters in practice is uncertain, though.
