I recall going into Sears back in the 1970s to their parts and service area. We had a table saw dating to the 1940s that needed some parts to repair it. I brought in the Model and Serial Number, looked it up in their parts catalog (paper then), and found the exact parts I needed.
Took about a week for them to ship the parts to me from their warehouse, but they fit perfectly and did the job. I think that table saw went another 20 years or so before it was retired.
The point is that Sears in those days made quality products and tools, and stood behind what they sold.

That began to change in the late 1970s. I bought a pair of high dollar binoculars from them, then found it had been made on the cheap, very cheap! I saw in the store some battery jumper cables with plastic clamps, shattered. Also a crackerbox welding machine with a shattered plastic adjusting handle.
