I think it's more likely that the sign was put up in the 1970's when LU
were starting to redesign Johnston. It might contain some experimental
variations that were not adopted for New Johnston.

Whilst on the subject of New Johnston I'm surprised that nobody
has mentioned alternative characters, or at least dots.

Compare pages 4 and 7 of the Fares for 2004 leaflet. On the
Carnet advert the full stops and the dots on the "i"s do not
have straight sides; on the Oyster ad they do.
