old chain saw

I have a " MALL " chain saw that I would appreciate any information on. This saw is from the early fifties, made in Canada, has a float carb with a rotating bar and must wiegh fifty pounds.

In the late 40s and early 50s there was a saw made in Canada that was called a Hornet, I Think it was made by Mall, it did weigh about 50 lbs. and a blade that could turn for cutting down , if I remember correctly it had a cast fuel tank about 4 in. wide and about 14 in. long across the top , the cylinder was under the tank horozontal ---Dave --
