The B2239 number turns up in Philips Navigator mapping c. 2007 for a road in Sussex, cutting off the corner between the A267 and B2102 near Cross in Hand.
The road is shown in present OS mapping as a spur of the B2102, so this number was either changed then, or was a mapping error in the first place. Confirmation of whether the number was actually ever allocated is still to be found.
Although "B2102" is posted at the northern end of the route (no number is signed at the other end), the number B2239 is indicated for this road on the East Sussex County Council map entitled Scale Map of Freight Route Network dated 2010.
