For about 50 years Sears would sell houses through their catalog - the whole house.
Since those panels are saying you can use Westinghouse, I'd guess that's who made them for Sears.
Sears does not make what they sell. They have third party manufacturers put Sears brand on things.
My mother in law owns farm she grew up on. Her parents did not buy the house but acquired it from relatives - and it was one of those "Craftsman" homes. Not sure when it was built, 1920's to 1930's I'd guess. We were doing some renovating a few years ago to get it back into good shape - it hadn't been occupied for 30 years. If you paid close attention you can find a number stamped on most boards - those would have corresponded to a number on the framing plans.
We did find on the back side of a piece of trim we had removed a shipping label. It was shipped by rail from Chicago to a nearby town.
They may have had more then one source for these over the time period that they sold them - the one that was in my Dad's house had very identical bus and breakers to many Crouse -Hinds panels made about that same time.
I know they have/have had different appliance manufacturers make their Kennmore appliances over the years.
It was very common for older Murray loadcenters to list ITE, Bryant or Westinghouse in addition to their own breakers as being acceptable.
And when they changed the name to Crouse-Hinds, the above still applied.
BTW, does anyone remember General Switch?
BTW, does anyone remember General Switch? Only time ever have seen them around here was in a now defunct farm store, somewhere have a pic of one, 200A Zinsco style main & the bus looked like it was cast rather then formed from aluminum sheet stock like most.
