Marilyn Raschka spends many of her weekends driving around unfamiliar neighborhoods, knocking on doors and talking her way into strangers’ basements. Once downstairs, she breaks out her flashlight and shines it along exposed beams, hunting for a letter and some numbers that are each no bigger than a thumbprint.
The 61-year-old resident of Hartford, Wis., is part of a small cadre of historians and passionate amateurs on a mission to identify and protect homes made by Sears, Roebuck and Co. About 70,000 to 100,000 of them were sold through Sears catalogs from 1908 to 1940. Distressed that the houses are falling victim to the recent boom in teardowns and renovations, their fans are scouring neighborhoods across the country, snapping pictures and sometimes braving snakes and poison ivy to poke around basements and attics for the telltale stamps that mark the lumber in most of the catalog homes. Because people can be shy about the state of their basements, Ms. Raschka brings along photos of her own messy cellar to persuade them to let her in.
There are some Sears homes around Madison.
