As the sabristi have already discovered this one, and the OSM edits
appear linked to Sabre Wiki edits, I will identify it.
In this case I am concentrating on A5191 (Coleham Head, Belle Vue Road,
Hereford Road) https://www.openstreetmap.org/#map=18/52.70122/-2.74811
Not a primary on the ground as can be seen on mapillary.
As Richard says this is legally a primary route, but the Highway
Authority have chosen not to promote it as a primary route, it is
signed at both ends as Belle Vue.
The Meole Brace end sign is

The signed primary route is via Hazledine Way, Pritchard Way and Old
Potts Way.
