Unit disks, when are they correct?

[BigBadDog]

Bearing in mind the Mk V was never officially issued (various un verified accounts that some may have been pressed into service post Dunkirk) as a service rifle probably unlikely to have unit markings.

One of mine has no markings and the other has a number, possibly a rack number, but neither have unit markings. IIRC unit marking ceased long before the Mk V was ever produced.
