(B) any amounts in trust other than amounts for which a deduction was allowed under section 170, 545(b)(2), 642(c), 2055, 2106(a)(2), or 2522, if such other amounts are segregated from amounts for which no deduction was allowable, or
(C) any amounts transferred in trust before May 27, 1969.

(3) Sections 4943 and 4944
