	In current versions of Samba, the read-only attribute corresponds
directly to the inverse of the owner read persmission (0200), irrespective
of any other permissions.  The major advantage of doing it this way is that
the mapping behaves consistently, regardless of the subject.

	I believe you can disable the read-only mapping entirely with "map
readonly = no" in your smb.conf if you wish.

	I suspect the NT ports of the shell utilites you are using do not
understand NT ACLs, and so synthesize permission masks from the file
attributes.  i.e., if the file is marked read-only, you get 0444, else you
get 0666.
