20" teens bike , Schwinn possibly

[Cheezer]

I picked up a few wood wheel bikes recently, and im curious about this little 20" one, who the maker might be. It looks like the serial is 138989 and the crank is a Schwinn AS 17. Im hoping some of you frame detail experts can help me nail it down.
Thanks
Dave

That's what i thought but wasn't sure. I suppose it's a 1917 or 1918 frame based on the serial number, crank, and the other serial number info i could find. j

Chitown info from another post (In 1917 they produced the 1,000,000th bike. 1916 bikes have 800,000 series serial #'s. I believe they started from zero after the one million mark)

Thanks, good to know.
