(a)
Into property similar or related in service or use to the property so converted, no gain shall be recognized.
(b)
Into money, and the disposition of the converted property occurred before January 1, 1953, no gain shall be recognized if such money
is forthwith in good faith, under regulations prescribed by the Franchise Tax Board, expended in the acquisition of other property similar or related in service or use to the property so converted, or in the acquisition of control of a corporation owning such other property, or in the establishment of a replacement fund.
