Can anyone identify this prop?

I'm thinking Dove?

Doves typically had a DH PD.143 prop. I can't see a part number anywhere in those photos, but If there is one anywhere on the prop, that would be a clue.

Failing that, blade length would help.

Thanks Dave. The blade length is 40 inches. Found some more numbers:

It's a three bladed controllable pitch prop, but apart from that there's not much more I can say about it. Do you have larger versions of the images in your first post? I cannot read the labels on the blade on these photos. Which way does it turn? Is it for a LH or RH (viewed from the back) rotation installation?

Viewed from the back, anticlockwise.

The number on the hub starting with PR1911 appears to be a blade assembly part number. The TCDS for the D.H.104 shows this part number in the list of approved props for the de Havilland D.H.104 Dove family: https://drs.faa.gov/browse/excelExternalWindow/35B7AF2E74CFC1C186257497007014DE.0001
It could still be a blade type that was used in various other applications... but the numbers do appear to fit. The assembly numbers in the TCDS have some additional bits that I can't find on your blade, it would help if the last bit of the blade assembly number would also match.

Thank you everyone for your help. Thank you Jhieminga for the information.
