Wooden Propeller ID Spitfire?

[vivienne]

We have a wooden propeller which I believe is from a Spitfire. It measures 59". Markings are SET..... (the rest is rubbed off) Imprinted on the metal is PROP 83092 1 and then 21148. Hand written on it is R7L48. I have photos but not sure how to include them! We are hoping to sell this once identified as we no longer have the space.

Hopefully Bob Gardner will be able to have some information on this. I don't have any information on British props from that era.
