Looks like prototype NPZ colours, but by that time, most SBB coaches had already been rebuilt with rubber bulges and extended coach ends.

B 50 85 20-34 113-4, photo (01.03.1984) in EA 4/84.

Text from EA 5/84: EA 4/84, Bild 3: Beim blau-weissen B' handelt es sich
um einen noch nicht hauptrevidierten Wagen, der Bestandteil der SBB-Leistungsschau bildet und für Bauprojekte wirbt.

Thus the coach was used for an SBB exhibition that went from station to station, before being refurbished.
