Here's a bit more.
"A new model of snowmobile, the B12, was put on the market. With its two rumbling exhaust pipes and its rounded silhouette, the B12 looked like a crouching wild animal ready to leap to the attack. Hurtling along a snowbound road, hugging the ground, it roared past, raising impressive clouds of snow in its wake. It was an unforgettable sight, one that fired the imagination and aroused the envy of those who saw it."
"Another model was put on the market in mid-November 1945. The C18 had been designed as a kind of snow-bus for schools. Larger and wider than the B12, it could seat twenty-five children. School transportation had long been neglected in Canada, and the number of children requiring transportation in the winter was growing rapidly. In Quebec, the first to buy these large snowmobiles were the rural Protestant school boards of Sawyerville, Inverness, and Clarenceville. Interest in the vehicles spread to other parts of Quebec, to Ontario, and to western Canada, and orders for the C18 poured in."
