Dave, Your welcome, glad to help out one of our Aussie friends. BTY, I was able to get the T.F. part #'s by going to the Tower Hobbies site, pulling up any Great Planes model, clicking on the Manufacture's link, and then going to their manuals list and looking under "discontinued models", and then reading the covering information in the manual for that plane. I then got the Tower hobbies part #'s from their site. It took a few minutes to get there but all of Great Planes old discontinued model manuals are there should you ever need to research one again. I have several older great Planes models but not the PT-17, that's a nice one! Enjoy.
