Back in 1942, Western Truck and Auto out of Winnipeg Manitoba Canada built a couple of Glass-Top busses for Brewster transport in Banff, they were well recieved and in 1946, 42 more were built.
These busses were used for a few years before they were "retired" from service and sold to the government, after the government was done with them they were all destroyed (as was the customary thing to do back then) But somehow this bus (#27) was not destined to that fate
