Re: Hawthorne /Rollfast year??
The frame is Snyder built for Mongomery Ward as a Hawthorne, Snyder produced bikes as Rollfasts but not with this frame. If everything on the bike is original to it (minus the front wheel!) then it is probably from very late 1939 or very early 1940. Earlier versions had straight down tubes and later versions used the throwing star sprocket rather than the swirl pattern on this bike.
