Jacobson 3 1/2hp

Manufactured by Jacobson Machine Manufacturing Company, Warren, Pennsylvania.

Jacobson produced a range of 9 engines from 3hp to35hp. 

This example is a 3 1/2hp, which interestingly is not listed in their standard range, which was later to be known as 'Bullseye' engines and marketed by Montgomery Ward.

This engine obviously predates that at c1912.

It is fitted with the Webster Magneto option.
