Can someone pls identify this pitman arm?

I picked up this RHD spindle, drag link and pitman arm in a deal recently.

It was described as a '34 setup.

I thought that all pitman arms from 1932 to 1948 were splined. This however is tapered and keyway'd.

Can anyone confirm what it is off?

Thanks

 

maybe it has been rheemed out and keyed to suit a different steering box.??????

 

Thanks for your reply Clem.

I forgot to mention - the tapered hole is smaller than splined shaft .

 

The taper and spline are definitely non-Ford...this is either heavily modified (ball end is similar to '34 Ford) or non-Ford. Any numbers forged into it?

 

Thanks for your reply Bruce.
I have found no markings or numbers on the arm.
I guess it's not early Ford.
