My copy of a '39 Schwinn catalog has "New World Lightweight Racer" model W3R that is very similar to the e-bay bike. Description includes; Finest American seamless tubing, one piece wood racing rims, popular oval shaped 5 pin type 3 piece crank and Lawson or Progressive drop bars. It also has an option of a one piece 6 1/2" fluted straight crank. Stem appears different than e-bay bike and I can't tell which way the rear dropouts are facing but it appears to be sold as a "racing" bike. Illustrations on the page are of the bike being ridden on the road not the track but in a race enviroment..
