"The Atlas Tool Mfg. Co., Inc., New York, N. Y. Filed May 10, 1929. ... Bent and Taper-End Bars, Telephone Digging Bars, Gooseneck Bars, Dumb-Waiter-Lock Bars, Bending Pins, Screw-Driver Bits, Bull Points, Box Chisels, Brick Chisels, Cape ..."
mark #283,773 (Seems to be 4 letters in a diamond)
Oddly, also, Obsolete American Securities lists:
"Atlas Manufacturing Co. Had office in New York. Dissolved 1886. "
