Hello Again! I finally made the trip with the camera, and brought back some digital photos! They're all a bit big to post here, so I've downsized a few, and if anyone wants the rest just let me know. After getting the car out from storage, and wedging my head into every nook and crany I could find, Neither my dad or I could find a chassis number! We did find other numbers though, and one Chevrolet insignia on the bellhousing. The chassis and driveline all mate together perfectly, no cuts, grinds or welds. All the chassis rivets are untouched. All the casting numbers on the engine, gearbox and diff all seem to be of similar sequence and casting style, so to our limited knowledge it's a Chevrolet of some sort, dressed up to look half like a Mercer to fool the untrained eye. It had us going! Every book or article we have ever found has led us to believe it was a Mercer Raceabout, but now with the information you guys have given us, and alot closer inspection, we have no idea what it is! Half Mercer, half Chevrolet, which would explain the "mercrolet" badge on the radiator. After all the confused looks and scratched heads, we decided to clean the plugs, top up the fluids, charge the 6 volt battery in the floor, fill and prime the fuel system, and nudge the crank handle. Off she went. We spent the rest of the day driving her around, and checking the operation of the fuel, brakes, steering, oiling etc. We had a ball driving around in a car that somebody put alot of effort into modifying. Pity it's not a Mercer, but we still dont know what it used to be!
