I love these old ads! Thanks for sharing them!
Seems from looking at the various catalogs and now ads from the 1960s, that the 26.75 kettle triangles went back and forth between 3 wire and 4 wire triangles.
I remember that old Sears logo too. Our old wood grain 1976 Garage door opener and my Dad's table saw (1970) had that version of the Sears logo on them.
We have Tagline alerts...... Well I call avatar alert! I couldn't resist!
