Sears started selling modern homes in 1908 and offered a few that year that didn't stick around long. The numbers were re-used but a different house offered. The authors of Houses by Mail had access to a large amount of catalogs but not all. Here is a collection of houses starting with the earliest that HBM didn't have access to.
Let's start with the Sears No 108 from 1908 through 1913. HBM listed some of the dates under the Sears Saratoga but until 1914 it was a different house.
Between the years 1908-1913 it went from having a bump out in the parlor to just a plain square living room.
Next we have the Sears No 120 which showed back up in 1909 through 1917 as a different house.
Next we have the Sears 128 which showed back up in 1911 through 1914. The 1912 reprint has it as the No 241 as does HBM.
Next we have the Sears No 138 which showed back up in 1911 through 1914 although not found in 1912.
Next we have the Sears No 158 which started in 1909 through 1913 but got a face lift in 1914. Floor plans were only slightly modified.
Next we have the 264P165 which started in 1909 through 1913 with a face lift in 1914. Floor plans stayed the same but it lost 3 fireplaces.
Next we have the Sears No 184 which was only offered in 1914.
Next we have the 264P232 which has the same floor plan as the 264P233 but with a porch roof instead of pergolas.
Next we have the Sears No 235
Next we have the 264P238
And the last house which appeared in 1909 the Sears No 303
Lastly Sears had a floor plan for a schoolhouse by only in 1908.
1908 Schoolhouse 500
