The two bars are a sign it's an HP Snyder built frame. What's interesting is that it does have the CWC shockmaster springer. CWC and Snyder both supplied frames for Hawthorne. The Snyder springer didn't come out until 1940, so it's not common but not unheard of for them to turn up with the CWC springer, which was introduced a year or two earlier. Thus I'd call this a late '38-39 bicycle. Doesn't make it worth any more but it's interesting from a historical standpoint.
