Derbyshire County Council living van plate

[steam engineer]

I have recentley found that my Bomford & Evershed living van No 91 was supplied to Derbyshire council and I would like to fit one of their owners plate to the van. Does anyone know the whereabouts of a plate or someone that may have one which we can measure/photograph to produce a pattern for casting, or cast from original. I would of cours cover costs. My number is 07794 399335 or send pm. thanks.
