Thanks Sam and Alan for causing me to rethink along my original lines
for wiring. The series connection of the field of course was for the
higher voltage and the connection I orginally settled on as being for
the low voltage was indeed for the high voltage. What I missed was the
other phasing possibility for the parallel connection while connected to
the low voltage.....when I found this, I noted that the speed up to was
faster (it took "about" 3/4 sec to speed up with the series connection).
This then gave me 2 valid possibilities for the windings and I further
found that there were 2 match marks for the movable shorting brush frame
which corresponded with a CW and a CCW rotation (likely an optimised
position as they weren't at the slot ends).

What threw me off the most was that the rotational speed was the same
irregardless of the connection (and torque developed was enough to spin
a significant but small load).

Good suggestion NSM on the book.....all the literature I read only
showed a series connection with no mention of other possibilities.

The diagram on the web page immediately suggested the dual voltage
possibility.
