2. Although USCIB declined to approve a•. similar proposal byLSIB in October 1951 (USCIB 14/154), I recommend that USCIB reconsider its position and concur in this request. 

,3. Inasmuch as there has been no U.K. re l to 

to rovide 

dated 18 December 1953), I do not propose to forward 

USCIB's views in this matter immediately. How~ver, I should like 

to have a decision on the request so that I ma Di~ector, 

GCHQ, as soon as I receive his comments on the question.
