Italian(?) Propeller identification

[Grifo]

Hi all

This is from an italian aircraft devoted forum; the owner (ain't me) of the artefact lives in Genoa, where Ansaldo factory built planes (i.e. Ansaldo SVA types) for Italian Army during the Great War.
We'd like to know if is possible to have some help in identifying this prop.

Here below is a total of propreller shape:

And here is a zoom on the codes impressed on hub:


So far, we have reasonably identified D value as diameter, P as pitch and bottom numbers as data of manufacturing of this propeller but we are unable to completely understand the meaning of codes visible on the top row, that unfortunately are partially scratched.
While IMO the last numbers and the "H" character can be read as "Hp 110" (thus a power rating) the first digits (the code of engine manufacturer?) sounds like "NI_2.(8?)(R?)(B?)", and we have no idea what the meaning of those is...
Can someone help us to solve this mystery?

TY everybody and cheers

Shape and dimensions match quite well propellers used on Le Rhone 9J powered Nieuport fighters, Nie.17 or later. But you are already aware about this fact

Hi Grifo,

I'm deeply interested in WWI Nieuport fighter family. there is any chance to obtain a drawing of this wonderful propeller?

Grazie

Hi, I hope you don't mind me saying so, and I know it's not your propellor, but I would love to see this propellor remain in original condition. Too often they and many other artifacts including complete aeroplanes are restored, and a lot of irreplacable information is lost forever. Cheers.

Ciao Grifo,
I can confirm that this beatiful propeller was fitted on a Nieuport 17. Ni 2 is one of the official Italian name for Ni 17. Power, pitch and diameter fit also perfectly. The last row is the manufacturing or test date, 21 August 1918.
Happy landings

P.S. Ciao paolomiana, mio nordico omonimo!

Hi all,
first of all please let me apologize for this late reply

And let me thank you all for your kind reply to my questions

@YavorD: yep, you're right I thought it was a Nieuport (indeed Ansaldo built Nieuports) but that code puzzled me

@paolomania: sorry, paolo I don't think owner of the propeller has drawings...

@aviationcollector: thanks, I'll forward your compliments to the owner. I agree with you and hope this beautiful object remains as is

@duedicoppe: thank you very much, your answer actually confirm my deductions

Cheers

Ops, wrong statement, was Macchi that built licensed Nieuport, not Ansaldo, sorry.
