Meteor T7 WA591 –

As some of you are aware a special Band of Brothers are restoring to flying condition Meteor T7 WA591. The photograph below was taken at RAF Driffield (not sure when though?). The image is an AHB photograph, sans any info printed on the back of the print. Thing is, it lacks any training colours (yellow bands on silver). Does anyone know when the aforemention yellow bands on silver was introduced as a training colour scheme?

Hope you can help…?

Best Wishes
