Early Girling......you can see the Girling Logo.
Pads & discs are the same regardless of caliper brand.
Unlike most owners on here who would recommend replacing the bearings I would say strip/examine & replace if necessary.
Clean bearings in petrol, examine the bearings and their races for wear (pitting/rust/discolouration etc) and if they look serviceable, repack with Multipurpose LM grease and refit with a new inner seal, you might also need to replace the stub axle nut each side (observe the correct pre-load for taper roller bearings) they require slight play to allow for expansion...absolutely DO NOT tighten.
