How to determine bike age?

[sideways]

Howdy, I recently got hold of a Schwinn Excelsior. I was told it is somewhere in the '35-'39 models. How can I find out for sure??? I've websearched quite a bit, but nothing really comes up. Thank you!

pix are the key,my man. pix of thhe serial #,alsohelp,mid '36,and back are kinda scrolly,late '36-mid '38 are tiny,tight blocked serial numbers,mid '38 on up are like the post war stamps. keith
p.s. sometimes you're fortunate enough to pull the crank,and it's dated,too.

Here she is. I've been told a '38-39 Autocycle-MODEL, marketed as Excelsior, but an Autocycle frame. Lots of non original parts on her. Reflectors, seat, handlebars, gooseneck, light, pedals. too name a few. Serial is D37747. Have been told original parts include, frame, fenders, chaingaurd, 2 speed new departure rear hub, rims.
