Thanks, and here are the two sites I use for small engine info. One is ANTIQUE & VINTAGE BRIGGS & STRATTON STATIONARY GAS ENGINES, and the other is ANTIQUE SMALL ENGINE COLLECTORS CLUB, www.asecc.com. These sites are full of info on these old Briggs engines, including date lists, and just lots of great info. The first site I listed is the one with the detailed date charts.
Looks like you have a great starting point. That engine has been kept well.
Where did you find the info for the engines? I have a 6b that I'd like to know more about.
