This is a ring type proximity fuze which differs from fuze AN-M168 in the design of the fuze housing. The housing for fuze AN-M168 contains a hole which accommodates a small roundhead screw. Since the screw is not used with fuze M168E1, the housing has no screw hole. Nominal MinSAT for both fuzes AN-M168 and M168E1 is 2,000 feet.
No information about functioning.
Nothing else to see.
