Greetings folk from Adelaide Down Under

I am requesting help to understand what is the correct and I am using a DHC-8-202 s/n 492 as an example for my question

Recently here in Australia the relevant registering organization "CASA" has decided to start changing DHC-8 (Dash-8) aircraft from De Havilland Canada to De Havilland Inc as the Manufacturer.

I know and understand that DHC is a subsidiary of Bombardier (or is now)

I am hoping that there may be some Canadian forum members that could possibly explain all the relevant Company changes and when that occured

regards from down under
