I just recently picked up a bicycle and I am having trouble figuring out what year it is and what it should look like. The serial # on it is on the bottom side of the crank and it is F40819. Its the cantilever frame, its got a springer front end on it. The head badge just says "the world" and has a picture of a globe. The rear wheel exits away from the crank so I am thinking that its prewar. I am wondering what year it is and I thought that prewar bikes were supposed to have a skip-tooth sprocket set up and this one does not. I was also curious if you would have pictures of the original bike with its original paint scheme so that I can restore the one that I found. Any information that you guys can give me would be much appreciated!
