OLDS Gas Power Company
Here are my two 1907 3HP OLDS engines. They are 18 serial numbers apart, the painted engine was mostly complete when I got it, the rusty one was another story! It had been through a fire and was completely rusted together, all the babbitt was melted out. The piston was stuck so hard that I had to heat the cylinder with a torch and drop ice cubes into the piston to shrink it and get the piston out.
