Hi,
Good information and a nice array of photos. I have one correction though, the last ad depicts a Snyder built Rollfast, not a Westfield bike. Some Snyder built bikes look similar to Westfield built bikes they were made by two different companies and one of the differences is the tank. All of the Westfield tanks used on their brands including Columbia and the Elgin Blackhawks and Falcons supplied to Sears use the tank with the round nose. The square nose tank was used exclusively by Snyder and used on the several brands they produced for including Rollfast and the line of Montgomery Ward Hawthorne Speedlines which were contemporaries to the Elgin Blackhawks.
I’ll add that both of the companies produced several different frames that were designed to use their in house tank, The Rugby Streamline that I posted in the winter weather bike thread is an example of a Westfield built bike and tank on one of their less common frames.
