No doubt Chris will be able to confirm but it looks to me as if both blades have been cut, rather than broken.

In some cases like this where metal props were substituted for wooden props during the usage period of an airplane a large surplus of unused props resulted and were sold off as surplus. You have one of the few that have a history of being mounted and obviously incurring a different fate.

To my knowledge Oxford propellers never counter rotated, though you are correct that some later versions used variable pitch propellers.
If you intend to have yours restored, be sure to read this thread first:

The L/H thread, diameter, centre bore and number of bolt holes are consistent with this application but, in the absence of a drawing number you would have to compare it to a “known” propeller to be certain.
PS: Coincidentally I’m a retired ATPL and current R/C plane flyer (well, I will be once we in the UK are allowed out to do such things). Nobody has ever given me a wooden propeller though, more’s the pity!

There's not much to go on, except that it's a left hand thread, which is common for a number of British built aircraft developed after WW1. The list of these is gigantic, and without specific drawing numbers all you can do is guess.

Large 87 inch prop ID needed
Hi Ive just been given by a widow a wooden prop as follows
Diameter 7 ft 3"
Hub diameter 9.5"
Hub Depth 6.66"
Hub bore diameter 3.25"
all sizes in inches. I am in Tasmania Australia and keen to restore the prop but would love it ID'd beforehand! There are no obvious markings I can see on the prop except a "T" but that could have been carved in after. Im a retired CPL and current RC plane flyer which is why the prop was given to me.Tags: None
