The 'engineering plastics', as they are now known, really came into widespread use through the 1950's, and were almost 'wonder materials' back then. Very cutting-edge stuff.
So, mentioning that Turner used Delrin became a selling point, i.e. that they were up at the leading edge of materials technology.
Brilliant Gadge!
I think you have responded with a fantastic summary here.
This is endorsed with Turner being the Australian maker first to introduce
the plastic catcher to Australia.
Many thanks for your insight.
