Spitfire Prop ID Help

Gentleman,

USAF Personnel stationed in the UK and need some assistance…

Found this, what I believe to be Spit Blade, advertised locally, and purchased at a low price so I took a gamble

Gentleman I bought it off of said he restored Spits in the early 90’s, and was given this by his company when they replaced propellers on some birds under restoration.

Blade has been, unfortunately, repainted, but the markings on the hub bottom are as follows

HRA 37018
RA 10046 RS

Also, on the face of the hub, just near the blade, are some small letters that look like a later add, showing PROP 59814 2

Prop is 60 inches tall base to tip, and 10.5 inches wide, with the base being 16 inches around

Any help???
