Authentic Westfalia?

[masvera8]

Hello,

I own a 1989 VW T25 Westfalia Joker Marsala Red Pop Top, I am wondering how I can tell if it is an authentic Westfalia conversion and more about the history of the van as there is no Westfalia data plate on the rock and roll bed.

This guide has some usfeul items, but nothing seems conclusive:

Are there any major give aways that would differ between a van fitted with a Westfalia interior as opposed to a genuine factgory built conversion?

Thanks,

Mark
