Prop information

I received an email today from someone with an old propeller. He gave me the following information from the prop itself, can anyone help in it’s identification?

DOWTY ROTOL
Prop Number 94699
3 (in a circle)
RA 4093/RS
R5 K (in a small painted orange disk – the R5 is written above the K)
R 10506

3 bladed, with adjustable pitch. Each blade is approximately 6 foot long, byt 10-11 inches wide, with a yellow tip. In the tip again appears ‘R10506.’

Cheers
