Rylard paint conversion

[greggles.w]

Seeking help, perhaps from maritime and/or aircraft modellers:

 

My current project, just commencing, is Karaya's 1/48 Short Crusader Schneider Trophy racer.  The aircraft is to be finished predominantly white.  But there are whites & there are whites .. !

 

My research to date is triangulating down to a particular product. References, including technical journals of the time, identify the finish as 'gloss white enamel'; 'Rylard seaplane white'; 'Rylard white undercoat .. [and] white enamel'.

 

I see Rylard is still trading today as a UK manufacturer of ship paints (no reference to seaplanes!). I could pursue them for a sample card of their white, but before hassling them I thought perhaps some britmodeller may already have confirmed an equivalent model paint match?

 

Any assistance much appreciated!
