My Briggs shroud has the embossed 5 vertical lines and B over S in red. Series # is: 904264 If I use the "N" guide, it is a July of 1948. but... before the Series no., it is stamped 8B-H Is it an 8?? Eights do not run that high. It has a recoil. (there is the usual instruction / specs decal above the stamped serial no. info)

Cool engine! Looks as though Briggs had, at this point, introduced their standard "Model Type Code" system. This means we can look at the last section of digits (5905140) and break that down as 58 (1958), 05 (May), 14 (14th day of the month). So May 14, 1958 If my memory serves me correctly, the 6B and 8B engines had began production in 1955 as the first all aluminum small engines from Briggs, before being phased out around the end of 1958 to begin production of the very similar and slightly updated 60000 and 80000 series engines, subsequently produced for many years. You may already be aware but the 8 stands for 8 cubic inch, translates to roughly 3HP. Hope this is helpful!
