not sure about the 1939 visit, but it was definitely Royal Drive for the 1951 visit
goldie, i hope you don't mind, i used your "then and now" photo of the top end of winchester at danforth in an article i wrote on my web site about royal drive --
Rediscovering Royal Drive
the pictures date back a couple of months, and it took me until today to finish writing it all up
all i wanted was this one shot of the end of winchester street just before the bayview extension --
things kind of snowballed from there as i added more photos and links and maps (to give that one photo some meaningful context)
but then because of the recent interest in royal drive on this thread, i buckled down and finished writing it all up this evening
i hope you folks like it, and that it was okay to post a link to my own site
