P-47D Help. Specifically 353rd FG

[Aviacom]

Hi,

I'm in need of desperate help.

I'm stalled on a build because of this!

 

I cannot find the size of the 'Checker' markings on the nose of the 353rd FG P-47's. They were from the 8th USAAF and known as the 'Slybirds'

I know there are 1/48th scale decal sheets out there with these markings on them, but I don't have one of those sheets that I can take a measurement from and scale up, do you?

 

Any help would be very gratefully received.

Many Thanks
