Where an instrument of amalgamation or transfer takes effect, the property held—
shall without any conveyance, assignment or assignation vest, on the instrument taking effect, or on the appointment of the appropriate trustees, whichever is the later, in the appropriate trustees.
In the case of property to be held for the benefit of a branch of the amalgamated union, or of the transferee union, "the appropriate trustees" means the trustees of that branch, unless the rules of the amalgamated or transferee union provide that the property to be so held is to be held by the trustees of the union.
In any other case "the appropriate trustees" means the trustees of the amalgamated or transferee union.
