The extensive and carefully considered opinion of the District Court, rendered pursuant to an evidentiary hearing, denying relief under 28 U.S.C.A. § 2255, has *933 been published, 264 F.Supp. 937 (1967). The factual findings cannot be branded as clearly erroneous. We are in substantial agreement with the legal conclusions expounded. We, therefore, perceive nothing to be gained by super-imposing another opinion upon that which has already been written.

The Judgment appealed from is Affirmed.
