The pedals on this bike were the same as yours by the way.
I did find a picture of an old enamel head badge with the world with winged wheel on top image, but the wording on the badge was 'BIEL' which had me confused until I discovered that Biel is the name of the Swiss town where the Cosmos factory is.
I also found a picture of a chap in a bicycle shop repairing an old Cosmos bicycle and the mudguards were the same as the ones on your bike.
Sooooo I think we can put the case to rest; - it's a prewar Cosmos
The question is, how much is it worth? It seems to me being a complete bike and decent shape it ought to bring a few $$$ being that old.
Ask the guy from American Pickers....he's a old bike fanatic....saw him pay 20,000 for a beat up first edition Shwinn.
