Hooray for "Hazel!"
The Baxter kitchen was originally furnished with what looks like an O'Keefe and Merritt gas range and an RCA Whirlpool gas refrigerator. The original opening in 1961 shows Hazel taking a freshly-baked batch of cookies out of the oven. As she pauses to enjoy the fragrance (and the "Shirley Booth starring as HAZEL" pops up on the screen), you can see the RCA Whirlpool emblem on the refrigerator door.
Ford Motor Company bought Philco Corporation in late 1961; in early 1964 there was an episode where Hazel and Missy (Dorothy Baxter) convince George to remodel the kitchen, at which time new TOL Philco appliances (including the Philco-Bendix Automagic washer and matching glass-window dryer) make their appearance.
If memory serves me, the Baxters drove Ford products, with the openings changing each year to reflect the new models:
Late 1961: White 1962 Ford Country Squire station wagon;
Mid-1962: Red 1962 Ford Galaxie 500/XL convertible (this is the car seen in the opening scenes when "Hazel" was syndicated in 1970);
Mid-1963: Red 1963 Galaxie 500/XL 2-door fastback hardtop with black vinyl top (you can see the "390" emblem on the front fender as Harold lines up for his picture with the family); not sure what car they used in the early l963 episodes, but it may have been another red Galaxie 500/XL convertible;
1964: 1964 Thunderbird convertible, possibly light blue; Dorothy luxuriates herself getting into the T-bird's back seat;
1965: 1965 Ford Galaxie 500 LTD 4-door hardtop; light blue with dark blue or black vinyl top; George can't find the car keys, but Harold borrowed them to "start" his miniature electric-powered toy Mustang (a rare thing then, even rarer now!)...
Ford's five-year sponsorship of "Hazel" ended in 1965 when they went to co-sponsor "The FBI" on ABC; "Hazel" ran through the 1965-66 season on CBS...
