These came from an airplane service company. The 1 and 2 blocks say Mitutoyo on them, the 3 block says Do All, and the 4 block says Webber(starrett). It appears they have all been checked and calibrated or certified at some time, because of the "calibration due date" sticker that is on the inside of the case, and the black and orange paint on each block.
