If the photo at <http://www.jproc.ca/crypto/kw26.jpg> had better
resolution, you'd be able to read the SECRET classification on the
equipment nomenclature label in the upper left corner of the top drawer. 

It says something very like 

SECRET
TSEC/KWR-26A

in the top two lines. 

The image at <http://www.jproc.ca/crypto/kw26_cmodel.jpg>, of a KWT-26C
and a KWT-26C, has the label as well.

The image at <http://www.jproc.ca/crypto/kw26_txrx.jpg>, of a KWR-26C
carcass that has been declassified (by removal of its guts), is missing
the label -- because once the guts are removed, it's no longer a KWR-26C
and hence no longer classified -- and, I suspect, because Daddy DIRNSA
would prefer that folks not see the nomenclature tag unless they're
cleared for that level and have CRYPTO access.
