Thanks for all the answers to my question, but I have decided not to buy
this particular scanner. The seller wants more money for it than I am
willing to pay.
It was good to see the list wake up and spring into action -- my thanks
to the participants, and to Tony Sleep for keeping the list going.
As I am sure you know Polaroid has gone through several owners in the
last few years.
I don't see an Australian contact. The closest seems to be Japan and
China.
I have emailed their customer support in the US to ask about access to
these parts, and will see what they have to say, if anything.
