Around the anode cooling block are two embossed metal labels, marked
as follows:
Ser no 34835 Made in Canada
British Type CV92 10E/CV92
Can Type REL7 US Type 4C27
Made for Research Enterprises Ltd by Rogers Radio Tubes Ltd.
The numbers 49691 are stamped onto the base of the cathode cylinder.
Overall length is 88mm, plus the leads. Width across the glass is 34mm,
and across the cooling block is 50mm.
See also CV972 which has two CV92s connected
together.

The valve in its box. The valve is held
in corrugated cardboard suspended by ribbons from the sides of the
box itself. Straw is used as packing. The box itself is marked similar
to those on the embossed labels, with the addition of the R.E.L.Order
No. A56583R. There are two stamps, one for Inspector and one for R.E.L.Inspector,
the latter being "AIR 2296 MAP 11869 REFERS"
