Identifying Model Year Whizzer Sportsman

[sportsman ride]

Hello, I'm looking for any help in identifying what year my Whizzer Sportsman is. I will include some photos of the bike and also list the Serial number / engine number I have located. I want to say it is either a 1950 or 1951 based on what I have read online. It has a Bi-Matic transmission on it, along with a front drum brake which is stamped Arnold Schwinn Co. Chigago. Any help is appreciated.

Serial # on frame - 3706

Engine # under crank - 308784 S

Number on cylinder head - 2251

Awesome, thanks for the confirmation. I'm looking for some information on testing the ignition system. I've turned the engine over with some speed using an electric gun and the most I am measuring is approx 1 Volt on the single alternator / generator. ( Trying to figure out why I don't have spark ). Is this something I should post a thread under the electrical forum section? Thanks again

I've never had to troubleshoot one

Maybe @mason_man a Whizzer expert can help you with this
