Norton snow mobile rig

I was in the snow last weekend, and vaguely recall an advertisement in the early 1970s of a Norton Commando on a rig with a ski for the front wheel, and two tank like treads/tracks powered by the motor. I think Cycle Guide may have been the magazine, and they may have done a test. Does anyone else remember this, or am I halucinating. I have never seen or heard of this since, but it would be interesting to hear what ever happened to this idea. Seems pretty innovative, but obviously wasn't competitive with snow mobiles.

SnowJob Twin Tracked Motorcycle Conversion Kit​

"It’s called SnowJob and was sold by Advanced Recreation Equipment of Mountain View, California in 1973. The conversion is a twin track assembly that your motorcycle bolts into after removing the wheels and it looks like the chain is used to drive the tracks. The motorcycle tilts within the tracks which would give the front ski the ability to carve through the turns. From the coupon in the magazine ad, you fill in the blank and indicate what kind of motorcycle you have, perhaps they would make one to order..."


I have a photo in my files of a Commando with two riders, but been gone a while and don't know how to post photos from my files.
