We believe that both our front and rear axles were made by the SHELDON AXLE COMPANY of Wilkes-Barre, Pennsylvania. Their own advertising from the period indicates that this company was a big deal. They claimed that it was the largest spring & axle company in the world. Our visits to Wilkes-Barre, lead Janet & I to believe that if this was the case, their home town doesn’t even know they ever existed. We visited two libraries and the Historical Society there and nobody seemed to know anything about this company. It was purported to have more than 1200 employees. Poof………gone & forgotten in 100 years. That’s a pity.
Our rear axle differential housing marked with “D 1”, not “201-D”
Regardless of the mark on the casting, we are certain that the differential is the SHELDON model 201-D. All the features cited in the advertisement (above) are consistent with our rear axle.
