The SWR with the apostrophe s is a grammatical error. The apostrophe
s indicates that the SWR is possessive, that the SWR owns something;
or, that the SWR is doing something. The apostrophe s is not plural!!


On the contrary, the plural of the letter A is A's. The plural
of the number 3 is 3's. It's not too much of a stretch to assume
that the plural of SWR is SWR's.

From Webster's: "apostrophe - a make used to indicate ... the
plural of letters or figures."


To take the argument well into absurdity (as if it
needed any help), we can discuss whether your
Webster's is descriptive or prescriptive.
good one
If I can ever help in increasing the absurdity of these newsgroups, I am
glad to do so.

BTW, all dictionaries are descriptive.
