The Mallard Coach Company of West Bend, Wisconsin manufactured the Sno-Wingfrom 1968 through 1970. During these years they used both the JLO (pronouncedas E-low) and Kohler engines. The JLO was used in the 155, 180, B295 and B295E models while the B399 was equipped with the Kohler twin.
One of the innovations on the Sno-Wing was a rear leaf spring suspension. It was claimed that this configuration assured a smoother ride and reduced shock and torsional stress. I guess that was possible. I'm not an engineer so I can't argue with the experts. Other features in the brochure described the "canting" skis, dual headlamps, wide track skis, extra high seat, 15 bogie wheel suspension, front and rear bumper, parking stand and bright tail lights.
As you can see there was nothing earth shaking about the sled other than the rear leaf spring and that must not have turned many heads in the industryor it would have been in use on other brands soon after. It appeared to be a rather conventional sled for the most part, just like the other 100 plus sleds built before the big "shakeout."
