Mystery Propellor

Hello,

I've just 'inherited' an old wooden propeller and would like to know if
possible, something about its past. On it are two metal plates. One reads:

DRG NO
DH5220 MR23
GIPSY MAJOY
D6' - 4" P.4' - 6"

And the other on the other side of the hub reads:

MAY 1940
K2973
69871

I've made a few investigations and believe that the prop is from a Tiger
Moth. But the serial K2973 if that is what it is, relates to a Hawker Hart.
So, is the serial number incorrect, or did the Tiggie have a run in with a
Hart with that number? I'm none the wiser, but am hoping that someone out
there, might be able to tell me more about this propeller.

I look forward in hearing your suggestions and would appreciate if possible
an email could also be sent, as I'm not a regular user of the Internet.
