Property of the kinds mentioned in this section, when used in business, shall be considered to arise out of business transacted in a state other than that in which the owner resides, under the circumstances following:
This section shall be reciprocally applied, so that all property of the kinds mentioned in this section having a business situs in this state shall be taxed in this state, and no such property belonging to a person residing in this state and having a business situs outside of this state shall be taxed. The assignment of a business situs outside of this state to property of a person residing in this state, in any case and under any circumstances mentioned in this section, is inseparable from the assignment of such situs in this state to property of a person residing outside of this state in a like case and under similar circumstances. If any provision of this section is held invalid as applied to property of a nonresident person, such decision shall be deemed also to affect such provision as applied to property of a resident, but shall not affect any other provision hereof.
