Hello Hepisbar.
Yes, a Qualcast 16 confirmed.

I have started a History Record here: -

This is a post WWII machine that I date to the mid-1950s.
It is a fully imported machine, and the tinplate covers that run
horizontally across the frame cross tubes indicate this is the
final iteration of the Great 16. Quite rare now.

Many thanks for saving this one.
Please keep us informed.
