Vintage Briggs and Stratton restoration part 1.

Part 1 of my vintage Briggs and Stratton restoration. As best as I can work out, this engine is from the late 1950's to mid 1960's. This model has a serial number rather than a code which would have given me a year. And from what I've observed on YouTube and history on the internet I'm pretty confident it's a 6HP. But I'm happy to be corrected if you know more.
