Serial Numbers for the 1/2 hp Upright Engine and the Fruit Jar are
1000 - 111301 

The Upright Magneto versions were likely in the later years of production.
99860 - 111301

The Fruit Jar engine engine would be within the same range as the magneto style.
99860 - 111301

This parts list is a scanned image of an old parts book. The images are large and will take time to load, but I had to make a compromise on size vs clarity
