F88 4wheel rigid

Hello to you all,

This morning (about 11am ) I was making my way southbound along the M42 between J5 and J4 , and heading northbound on a stepframe trailer was a F88 4 wheel rigid. I am saying F88 as it had a chrome grille (though Im sure those of you as F series expert will tell me otherwise) and had a dark royal blue cab, and flatbed body.

Does anyone know who’s it is, as I seemed a fine example of a rare vehicle
