The last versions of B.P. Arps and Adolf Langenfeld’s snowmobiles were the ultimate refinement of the type. A considerable power increase over the Model “A” and the earlier V-8 powered cars made them all the more useful. The pages below describe a planetary gear reduction system at the wheel that gave a a final drive ratio of 8.22 to 1. In combination with the stronger V-8, this probably made for some real stump pulling performance.
In studying photos of the Snow Birds and Super Snow Birds with standard Ford bodies, it appears that there might have been a clearance issue between the door bottoms and the tops of the tracks (note the top photo). Many period photos of some of these conversions do in fact show shortened doors. If any of our readers have first hand experience with one of these, we would like to hear if this really was the case. It was not a problem on Virgil White’s original Model “T” design, of course, because the tracks were mounted well aft of the doors.
To wrap up the Snow Bird saga, we are left with a minor mystery. Research we did for this series of posts indicated 1939 as the last year of Super Snow Bird production. This includes the official company history of Amerequip, successor to the Arps Corporation, who we think would probably know about such things, but below you see a catalog for these machines dated 1940.
It is entirely possible that no 1940 models were ever manufactured and that the catalog is as far as the new model ever got. So, once again, we will ask you, our knowledgeable readers, if you have any information about this. You can see our earlier post about the Snow Birds here. Thanks again to Terry Harper for sharing the brochure pages.
