Wrong. The drawings belong to the Peoples Mosquito in the UK and they are NOT public domain. Our organization has been trying to get access since they were found with only a few drawings being passed on to us. Attempts to get more have fallen flat.
Avspecs have done some excellent work but they are NOT the "primary authority". I would suggest that description be shared amongst many reputable organizations and that the folks at the de Havilland Heritage center to be at the pinnacle.
And I'm not a "recycler of other people's recycled information". As a board member of the Calgary Mosquito Aircraft Society and active member of the restoration team working on Mosquito RS700 I do have access to first hand info, some of which I have posted above.
