In 1948 W.R. Lummis invented the Original KEY-BAK Self-Retracting Key Reel. As a switchman on the Pacific Electric Railway in Los Angeles, he saw brakemen and switchmen injured when their dangling key chains got caught on moving trains. Lummis had an idea for a reel that would keep keys within reach at the wearer's side, safe from snagging on moving rail cars and machinery. His idea became the first KEY-BAK. Today, six decades after the first KEY-BAK was produced, millions are in use worldwide in more than 20 different professions. This cache is a tribute to inventors all over the world and to American ingenuity. Inside it contains a Key-Bak Self-Retracting Key Reel for the FTF. Solve the value of each key so that the total equals the number at the end of each row and column. To get the correct coordinates enter the value of the key using that value found in the following ordered pair.
N 34° 03.ABC W 117° 33.XYZ
A = (34,34)-(45,34)
B = (49,34)-[(45,34)+(37,34)]
C = (37,34)
X = [(49,34)-(34,34)]+(37,34)
Y = (49,51)-(34,34)
Z = (37,34)+1
