The IDs on the RF door and on the face of the rear seat/bed
are Westfalia IDs.  The one in the driver door frame is
Volkswagen AG.

My Westfalia stickers have a serial number, but it is not
the VW VIN serial number.  The VIN serial number is on
the VW sticker, plus the corner of the dash and also
on a cross member under the sliding door.

I've seen the RF Westy sticker in different places--on the
door, just below or just behind.  Some identify the vehicle
as an RV--I think Oregon.
