This 84 Westy has a temp gauge built into the analog clock. There is
also a second one mounted on the dash directly to the right of the
instrument cluster housing.  It's round, the mounting case is the same
chocolate color as the dash. It looks pretty factory-installed. Near as
I have been able to see, the PO made no modifications to the vehicle
whatsoever. I can't find any mention of this gauge in the Bentleys
manual. It's presently non-op, but I might could fix it.
