You can read about them here. They were made by Lincoln Car Works for Sears to sell from catalogs. https://en.wikipedia.org/wiki/Lincoln_Motor_Car_Works
They had to compete against cars from Ford that were much faster, up to 45 mph for the Ford Model T, compared to only 25 mph for this Sears model.
“Timken Roller Bearing Axles”? There’s a company here in the midwest US called Timken, they make belts for vehicle engines and other applications. This stood out to me, because Timken closed their plant here recently after about 40 years of operation. So, uh, thanks for surviving all these years, Timken? Mixed feelings.
Wild! Founded in 1899, and they specialize in roller bearings, so probably the same company from the ad. They split into two companies in 2014 according to wiki, and then there were mergers and stuff, so it’s a little jumbled. But they still do bearings for modern vehicles.
