Penn Acco

[BillP]

I hope I"m where I want to be! I've had trouble serfing this site since the format was changed. Anyway, I'm trying to find info about a lawn mower I just acquired. Its a cast magnesium deck with PENN ACCO cast into the front. It has an 18" cut. The power is from a B&S 6B-HS engine. The deck is painted bright yellow and the engine is green. Who, what and where is Penn Acco? What's the age of the mower? B&S tech help told me the engine was manufactured in 1953. This was based on the type; 900170, and serial #; 1032696, that I related to them. They could not give me any logical meaning to the numbers. Any help, info, or leads would be greatly appreciated. Thanks. Bill
