Bob -

I looked into their offerings a bit when helping Al on the Scott-Phiefer Antebellum House, when the hysterians there mistakenly assumed the roman numeral carpenters marks on it had to mean it was a "kit" and so obviously a Sears product.

It was built fifty years before anything they offered, but the buildings you've been looking at fall right in the appropriate time frame - http://www.amazon.com/Sears-Roebuck-Book-Barns-Reprint/dp/0976209616
