Sure does look pretty, Brown Chicken, seems almost a shame to use it . I had to fit one of those tension release guides to my 111W117, as that model doesn't normally have one. It was obviously a generic piece and required a bit of judicious bending to get it to work. The hole that slides over the shaft didn't quite line up and when I got that working I had to tweak a couple of other bits to get it to push the pin. Just make sure there's nothing binding, it should move freely. I got there in the end, but it wasn't a simple "drop it in and it works" thing.
