T25s came from the factory in various guises; panel van, caravelle, combi, etc..
AFAIK the only camper conversion of the T25 offered by VW were the Westfalia conversions.
The various conversion companies would buy a base van and convert it; the base van being one of the standard factory offered variants.
Our van seems to be a fairly basic Combi as a base, but also has a 'Camping' badge on, which looks very much like an original VW fit item. I have seen them on others too.

So, is that a VW thing? In which case was it something only offered to aftermarket converters? Or was the badge added by Autohomes?
Just curious,
cheers
