I would say yes. I never heard of anyone moving the serial
tag from an old CRT. Only case I would believe would
be newer sets that under warranty had a strip of tags to
prove you opened the set ( NAP ).
With Zenith you would find matching #'s on the box,
back, CRT & engraved in the chassis that you could often see
through a slot. Saved my ass once when some anal orifice
claimed I swapped his back for another !!! Still cant figure
why I would commit such a felony.
