The Rotol prop R22/4F5/8 is possible and the blade could be one of these for the prop type used. Unfortunately there is not more of details at the bottom of the blade in the pic you posted above.
The drawing number of the blade is 10167.
The number 23 33 , actually the B 2333 seems to be the block/batch number of either the blade or the hub adaptor. However I'm not sure but there can be one more digit seen at the center of the blade. Probably it is the digit "5". But I may be wrong.

 
Hey 53B,

As far as I know, the main body of all military Rotol propeller wood blades were painted black or very dark grey as part of the finishing process. So this is not the original finish from the factory, and I do not believe it would have been used on an active military aircraft with the finish it has now.

As to what clear finish it had originally, the 101xx series were (I think) Jablo wood, so if Wurger is correct and 10167 is the blade Drawing Number, then the pink dot may be to signify to whoever that it is a Jablo blade. Up to now all the 101xx series blades I have found data on had the post-war type Rotoloid(ie Rayoid) covering from the factory. But i do not know how to tell whether the finish on the blade is this type.

Of course it hasn't been used in this state. The blade was stripped of the covering. Then , what is very likely, it was varnished and polished in order to get the current appearance. The small pink dot made manually, could replace the origin disk for the Jablo blade. Unfortunately it is not too much to ID the prop blade. Usually there were serial numbers of all baldes used for the particular prop printed in the disk. Additionally , the serial of the particular blade was printed there with a slightly larger font size or just bold there. For instance, if there were four serials the prop was 4-blade prop but if there were five of them the prop was the 5-blade one.


The question to 53B though .. what kind of the metal is for the sheath? Steel, brass?
 
Hi, I think the propeller blade has been stripped of the rotoloid or rayod covering which had been compressed. For this reason we see the crossing marks on the woodwork. The surface is not varnished, it looks like a layer of plastification with cellulose? When do you think? See pics the rotolid can be stripped off it seems.

On ebay UK there is currently a seafire mk XV propeller that looks very similar to mine when do you think?

The blade in your earlier posts looks quite shiny. As you may notice the wooden core of all Rotol wooden blades with damaged covering look matt but not gloss. So it means that the wooden surface could be protected with a gloss varnish. No matter what kind it was of. Also it could be polished in order to make it appearance more attractive.

Anyway here is a pic of the RA.10167 blade for Seafire Mk.XV prop. I think your looks the same and the one you posted above as well. The blade hight (length) was 58.75" = 149cm


There are possible marking that could be found on the blade ... note the pink/red disk for the Jablo wood.



the source: the net.
 
They have the same hub marking
RA 9731 . So my model would probably be a Seafire mk XV or (mk XVII propellers shortened to reduce the rollover during landings particularly frequent on the aircraft doors) so model with 4 blades.
 
Thanks, I have a total height of wooden blade + metal bottom parts = 58.66".
I don't have the rotoloid anymore but we can see the wood grain that was wrapped by the black heated rotoloid.
 
Otherwise I was thinking of the Spitfire mk XIV or mk XVIII version with 5 propeller blades and a griffin whereas the Spitfire mk XVI had an American built Packard model of the Merlin 266.
 
I need your insight; were the Seafire mk XV and Spitfire mk XIV in operation at the end of the conflict between late 1944 and 1945?
Do you have any information on these 2 models in operation?


SEAFIRE MK XV

As memo serves, the Seafire Mk.XV are the post war planes. These came into the service in the April of the 1945 and didn't take part in operations at the end of the WW2.
Contrary to the Mk.XV the Mk.XIV participated in the operations during the WW2. The version of the Spitfire started its servicing in 1943 and was used for fighting against the V1 missiles for instance.
 
I can't find the plans with the dimensions of the different sections to know if they are ROTOL of Spitfire mkXIV or Seafire mk XV? Does anyone have any measurements to narrow the search?
Again, many thanks to all of you for your answers.

I meant measurements from drawings: length and different widths.
Do I have to calculate twice the length of the blades + add the diameter of the shaft that goes through the hub?
How big is the hub shaft anyone knows?

I would say your prop blad has already been identified. So what for the dimensions of the hub? Sorry but don't grasp.
