C. M. Armstrong Building. Clifton Martin Armstrong (1888-1951) was instrumental in the early growth of Northern Gaines County. He was involved in several significant area land deals, including the sale of town lots when Seagraves was founded in 1917. He served as mayor for twelve years and, with his wife Carobel, daughter of pioneer Texas rancher Col. D. H. Snyder, was active in community activities. In 1926 Armstrong built this structure to house his Seagraves Motor Company. After a fire destroyed other buildings on the block in 1928, a bank and the post office were temporarily located here. 1981 #595
