i've been rather lucky today. After i left the tram at a station, i was on the way to the underground, and saw another streetcar was arriving. I went a few steps back to read the number, i've been looking for the first streetcars of the current series for quite a while.
It's been 4001, the second of the SIG built Toronto streetcars! I've just borded it to go back a stop, but saw a couple of differences, most obviously no Hawker-Siddley plaque of course.

just saw the first Hawker-Siddley built CLRV tram, number 4010. It's on 505 Dundas.
Tram hunting is the new sport for sdogs ;D
You had some good luck there!
