I saw the pictures of the one on here some time back, is that the one you got?
If so, yep, its identical, and should fit any victa with a thumb release catcher, even the twin, but also, Mustang, Vortex, Silver Streak, etc..
I love these chutes, they came standard with some models back in the early 70's, and have been optional since, i live in an area where rocks are a substantial issue when mowing, but the grass is too thick and heavy to be bothered with catching, so i have a chute for every mower i can find one for (which is 3 right now, this,one, a VC-160, and a sapare VC-160 chute i edited to fit my auto drive.)
