From the 11/26/07 draft of the Third Edition of M14 Rifle History and Development:
"The Springfield Armory, Inc. story begins with U. S. Air Force veteran Mr. Elmer Ballance of Devine, Texas. His last name is correctly spelled with two lower case letters “L.” He started his business, L. H. Gun Co., in 1960 while stationed at Lackland Air Force Base in San Antonio, Texas. The base had a housing subdivision named Lackland Heights. To save time writing, he named his company, L. H. Gun Co. “L. H.” is an abbreviation for Lackland Heights. While serving in the Air Force, Mr. Ballance shot the M14 rifle in competition on the All Air Force High Power Team. Staff Sergeant Ballance earned U. S. Air Force Distinguished Rifleman Badge (# 42) before completing his military service in 1964. After that, he built match grade M1 Garand rifles for competition shooters. At some point, L. H. Gun Company also produced and sold .30 Caliber M1 Carbine ammunition in boxes of fifty cartridges."
