Orig. WW2 RAF or USAAF metal PILOT'S CHECK OFF LIST checklist take off / landing For Sale

a recent estate find..
an original WWII era pilot's checklist for take off and landing. I'm not sure which aeroplane this would have been affixed to. This was found with along with some Royal Air Force manuals, photographs, gear, and other ephemera of a Canadian pilot who flew for the RAF in WW2. He was trained at RAF Hereford ( now known as RAF Credenhill ). I listed the Air Ministry publications and will list his jacket soon. I am assuming this would go to a British fighter or bomber plane as i found it with his other stuff, but i do not know for sure.If any member out there has more information on this plate please do share.
a pretty nifty and unique item.
I'm offering this as found,very nice condition. please examine photos and ask any questions you may have.
