Prop hub age ?

I am restoring a prop hub box with the following markings

G 2032 No11
270 HP RR Falcon
Drg P 3053 RH
D2950 P2850
9 23

I assume an F2B as similar to this one

Are the last set of numbers a date ?

Thank you Mike given the rating as 270 hp RR falcon I had assumed it was post ww1 and likely early 20’s. Pleased to hear that there is a date on some props.

I think it very likely that is the production date.

Olly that is the question – whether that is the date or another prop reference.
