B&W Matrix 2 series 2

Hi all. I have got a pair of these speakers in perfect working order but they have some cabinet damage, mostly along the top edges. Also the grille mesh is vey shot at, and needs replacing. I have no idea what these are worth; my question is really A) are they worth having the cabinets refurbished, B) where and how would I go about this if they are, C) does anyone know how the grilles come apart so the mesh can be replaced?
Anyone know how these are valued in good condition?
Is anyone interested in buying them as a project or as spares?
I repeat, they work fine & there is no damage to the drive units at all.
Would be interested to hear from anyone on the subject.
