Ted, not brake fluid, that's a windshield washer bottle, something all
Amphis here need by law, not factory fit but would have been dealer fit
before road registration.
Other differences, front indicators (turn signals) are not conical and are
in 2 parts, no bilge blower, no flame trap on carb. All that is factory
original.
Apart from the Swiss spec Amphi, (another on this page
http://amphicars.com/acpics.htm ) there was also a police spec Amphi - that
didn't have sheet metal differences but was substantially different from
standard. Pics here

Oh and a few European cars also had reclining front seats, there is a lever
on the side that you use to adjust seat back position rather than the
knurled button things, I've seen four cars now with that reclining
mechanism.
