I just added a CV8067 to the site. This is one of a number of Haltron valves I have noticed recently on eBay where the valve just carries the CV number. All those I have noticed are in the CV8xxx range.
Now K1001 does permit this but specifically when it is “impractical, on account of physical limitations” – see here (pdf) section 4.1.4. It is hard to see how a valve such as this example could not carry the full CV information. On on a subminiature valve, but not here.
The valve came in a Haltron box with no markings, and a label attached giving the CV and NSN numbers.
Looking at the valve the printing is slightly different too, as if the original Haltron marking is the original and the CV number added later. There is no obvious evidence of the civilian part number being removed, but of course it may just have been cleaned off sufficiently well as to leave no trace.
