To me it looks like a hawthorne but i am not sure of what year it is. Definately pre war.
It's not pre-war and it gets technically tough nailing the exact date on them frames..
1st note is it's near the 1st generation past 1941 "pre-war"
The second cross bar is brazed, and for the rear dropout down tub bending I'll also say the top bar is not brazed whereas pre-war is brazed and that lower down dropout tube is straight on pre-war. . the next newer line after yours only has 1 or two places with brazing anywhere on the whole frame post 46/7. and the rest is spot welded.
Do I see your fender mounted on the drop out?
the drop outs indicate transitional changes, pre-war will be brazed on and the bottom of dropout has an ear, bent outward hanging on it, prob designed to stop the drop stand, the only holes are near that lower ear for mounting drop stand. . Believe there's a noted 1st war era brazed, but the ear is gone, they've begun using kick stands, then they'll have top side electro tack welded with bottom side brazed, no ear, next both tack welded and no brazing on the dropout but may have brazing on another area of bike, and finally by 1950's the whole frame is spot welded.
Along with this transition, 1st war era, does not an oval hole for chain guard screw mount, 2nd war era/post war get it, next gets another hole for accessory, fender/rack mounting and later that accessory hole is carved unto a U shape. Presumably to make accessory easier to remove.
Shoot a good clear photo of the dropout on he chain side, also show what holes were drilled in it (remove any fender/rack braces if in the way) , I would not expect to see a hole for accessory; fender/rack, in yours, show exact spot would be important if it's there, where your fender is mounted on to guess whether one was drilled later, or it's original. . and where/how the whole drop-out is attached to the frame and ya might be able to pin it down within a 4 year margin.
Also expose the serial numbers from left to right to see if there's a C with a small w inside that C, spaced 1/4" - 3/4" past the serial number set or near edge of crank housing. . Is there only a C with w, or a letter before the C. "Cw, (Illustrating there's a small W inside the C)., or DCw, (there's a letter before the Cw) " by 50/51 the Cw will be preceded with 2 numbers dating it, Cw 51, 52, -55/6. I spect yours, for that lower brazed bar, there won't be an extra letter before it.
And you'll begin estimating its date, most especially because it's retail style painted, (post war, CWC advertised no builds or sales of retail bikes during the war) I'd guess, late 44/46 frame and painted/build date - 45/46. Who'd sell bike first, Wards, Western auto etc, or CWC? odds are CWC badged their 1st post war painting so Branding other names % leans on 46 +.
Drop out keys war era/post time frames, and periods where CWC's stamp changes : 42-46/8, A-ZCw: 47-49, 50 , and 50's Cw
