SP also had American Comm Dept locks---LBYWS-1 on the "civilian" keyway and later LBYWS-2 on the R1 keyway after they realized the folly of the first (the cuts were the same on both by the way). LBYWS was the key code for the Eagle Comm/Tele Dept locks. There was also an SP Tool House American, also on the R1 keyway. The old Eagle Tool House locks used JNHFW key code. These were all brought about after Eagle Lock folded. The Signal American came about as a result of increased vandalism and dates from about 1972. The Wilson Bohannan locks Signal used before that were small with brass shackles and easily popped of.
