PIR-2 is a modification of PIR-1 by replacement of instantaneous detonator with delay detonator (0.02 second delay). This one appears to be a Model 0. Development was begun in Feb. 1944. 6,000 Model 0\u2019s were manufactured by Caltech in April and May 1944, for tests by the navy. After standardization 96,000 Mk146 Model 1 fuzes of Buord were converted by Caltech to Mk157, Model 0 fuzes. This occurred in the period Oct. 1944-March 1945."
