I’ve been doing a pretty good job of popping up right after being announced lately. The date on this bike is 1947-1949. The Bike was made by Cleveland Welding for Western Autos and, except for the missing headlight, it looks to be quite original (it looks like it came with a Delta front-load torpedo headlight.) The frame and tank style are known generically as the CWC 3-Gill and the easiest way to separate pre and post war versions of this frame is the inclusion or absence of drop stand stop tangs as part of the rear dropout blank. After the war CWC moved to the use of kickstands over drop stands and removed the ears. The bike is further dated by the deep curve of the down tube. 3-Gill frames built in 1945 and 1946 maintained the prewar style shallow curved down tube before incorporating the deeper curved design used on the new Luxury Liner frames. These frames continued in production after 1949 but for 1950 the design of the rear dropouts was again changed.
The serial number on the bottom bracket (including the Cw suffix if there is one) can date the frame more closely
