My husband and I purchased our Sears catalog home this past April. According to our records and researching the old catalogs, we have a 1930 Maplewood (#3302). After reviewing old catalog pages, we believe the floor plans were reversed compared to the original. In fact, according to the original blueprints, which we have, the words “This plan to be reversed” appear on the top! Was it commen practice to reverse the floor plans? Does this lessen the historical/collector value of the house? Do you know where we can find a front entry door at a reasonable price?
