Good Morning Bob,

Your prop was designed by the Royal Aircraft Factory, indicated by the letter T in the drawing number. It was number 26 in a batch of 100, numbered G281, which dates it to late 1917 or early 1918. It was a standard prop for the SE5A from February 1918. The design of the prop existed before then. This was the date when the Air Board instigated the system of preferred props for aircraft, often (perhaps always) by competitive trials.

All WW1 props are rare. Within that category yours is particularly rare. I have only seen one or two others in the last fifteen years. Drg nos AB8080 and AB7673 occur more often.

With kind regards,

Bob
