Here is a message from Peter Lewis, which may be of interest:
I have posted some notes on the TEAL flying boats plus a considerable number of photos at the Wings Over New Zealand forum:

You may find them of interest.
You would be very welcome to join the forum and tell us of your experiences with these Empire, Sunderland, Solent and Catalina boats.
