In the 1970's, Lusco saw many consolidations. Mr. Steele passed away in 1976 and soon the company ownership was brought entirely into Gilkeson hands. In additions to the sale of Excelsior Brick, Lusco operations in Kansas City and Oklahoma City were suspended and the properties were sold. In 1977 Bruce Gilkeson (son of HBG III and grandson of HBG II) assumed operational responsibilities.
With the third generation involved, unburdened from running remote manufacturing and distribution operations, the focus of the company turned to providing Wichita and Kansas construction markets with superior service and the finest brick, stone, and masonry products available.
