Is this a real Winchester Type III "EW" safety?

Brian,
I'd like to personally take this time to say Thank You on your 'Outstanding Articles' in the last couple CC Newsletters about the late 6 and 7 mil Winchesters.
Now that I think about it, I recall your picture showing the EW marked rotary safety.
Please pass along some Thanks to Newscotlander also.
We sure miss his input here on this forum.
Both of you deserve credit for the hard work put into these articles.
You've shown again that the newsletter is priceless.

Sincerely
Charlie
