Nice progress here, it's coming together very well.
I am indeed tempted by 193, Nigel, but would have to make some assumptions: does the dark blue go under the fuselage as well? I take it the upper wing crosses have a dark green overpainted background? The lower wing crosses on CDL background? But quite doable, I would make the green cowling and blue tail quite bright shades... just me!
If there's no photographic evidence to the contrary, IMO you can make whatever assumptions seem logical regarding the scheme.....
