Guy,
The later motors are the round body - early was rectangular/square. All the
cogs are the same size but have the crank pin in a different position to
produce more or less sweep. Spridget is 110, maxi is 90, Marina is 120, Mini
is 110 or 120. Same motor used on lots of things BMC/BL/Rover. Metro is
different drive mechanism (direct).

The larger driven cogs are stamped with the angle of sweep of the
wiper arm. A worthwhile swap is to use the driven wheel from a mini
which increases the sweep to 110degrees. (standard is less, I think
90)
I guess those funny 3 wiper arm setups that come on the later USA spec
cars must have a different ratio again.
