Technical Ancient Cylinder boring machine

Machine is still working. I had some trouble with the old cloth wiring. Sparks, funny smells and dimming lights. So I ended up rewiring the motor inside and out. I had to do some repairs to the windings. I met up with the guy I got it from as he called me to tell me he found some more parts for it. Another boring head and the bronze crank handle. I asked him some questions about the machine and he said he got it in 1964 from a gas station that had been using it to do engine repairs. He only used it to do a chevy engine then in 1964 and its been in storage in his shed since then until I got it
