In any case in which an insured has been denied or would have been denied premium waiver under section 602(n) of the National Service Life Insurance Act of 1940 or this section solely because the insured became totally disabled between the date of valid application for insurance and the subsequent effective date thereof, and in which it is shown that (1) the total disability was incurred in line of duty between
October 8, 1940, and
July 31, 1946, inclusive, or
June 27, 1950, and
April 30, 1951, inclusive, and (2) the insured remained continuously so totally disabled to the date of death or
June 8, 1960, whichever is earlier, the Secretary may grant waiver of premiums from the beginning of and during the continuous total disability of such insured. Application for waiver of premiums under this subsection must be filed by the insured or, in the event of the insured’s death, by the beneficiary within two years after
June 8, 1960, except that if the insured or the beneficiary be insane or a minor within the two-year period, application for such waiver may be filed within two years after removal of such legal disability, or if an insane insured shall die before the removal of the disability, application may be filed by the beneficiary within two years after the insured’s death. No insurance shall be placed in force under this subsection in any case in which there was an award of benefits under the Servicemen’s Indemnity Act of 1951 or of gratuitous insurance under
section 1922(b) of this title. The amount of insurance placed in force hereunder together with any other United States Government life insurance or national service life insurance in force at the time of death, or at the time of the insured’s application for waiver hereunder, may not exceed $10,000 and shall be reduced by the amount of any gratuitous insurance awarded under the National Service Life Insurance Act of 1940. Waiver of premiums under this subsection shall render the insurance nonparticipating during the period such premium waiver is in effect. The cost of waiver of premium and death benefits paid as a result of this subsection shall be borne by the United States.
