Buffalo Master Mechanic Retires George A. Leo, 60, Buffalo, N. Y. Fire Department Master Mechanic, retired April 1. During the 12 years he was master mechanic, he responded to most Buffalo extra alarm fires so he could observe the fire apparatus in actual combat operation. Mr. Leo also developed new fire equipment when he was not repairing Buffalo’s apparatus. He recently built a searchlight truck equipped with nine big movable lights, several smaller portable lights, masks, saws, and other rescue equipment. The apparatus.
