That is a Series screen that has been modified to allow the upwards hinge (don't recall ever seeing it as an option in the old books). Opening screens were popular like that before & after the war but went out of favour later on.
Anything is possible but you would have to use a Series roof as the top of the windscreen is lower and a different shape to a 90/110 screen.
The obvious answer is to go with the normal forwards tilting screen although not really an option if you have a hardtop fitted which is why that modification may have appealed and why I assume you are considering it?
