change > change out

[Douglas G. Wilson]

On-line newspaper search shows this "change out" from way back. I don't
recall it even from the 1970's myself. Random examples:

----------

_Odessa [TX] American_, 16 Feb. 1958: p. 5:

[Improvements in telephone equipment]

<<In order for the cutover to be made at Kermit, it required a change-out
of 126 first selector switches and the modification of all inter-toll and
toll transmission switches.>>

----------

_Valley Morning Star_ [Harlingen TX], 21 Nov. 1948: "Fair Section", p. 6:

<<Electrical service continues to plunge through this 69,000 volt circuit
during the change-out of a broken pole by this CP&L Valley crew.>>

----------

_Coshocton [OH] Tribune_, 24 Aug. 1967: p. 3(?):

<<She said her husband was going to change out a three-way electric light
switch that very afternoon.>>

----------

At a glance, it seems like the noun "change-out" may predate the verb
"change out".
