Pedal Ass'y ID needed.......'39 Ford?

Can anyone ID this pedal ass'y for me? I got these with a '39 Ford Tudor. It looks as though a piece is broken off...........any ideas??
Thanks.
Update.....Numbers on the brake arm are 68-24558

 

Not a 39 assy. Probably 37-38? Look for a part number on the arms or mount.

 

Numbers on the brake arm are "68-24558".............That help?

 

I believe that's a 1936 part #
it has the brake arm on top for pulling the mechanical brake, a `39 would would have the arm on the bottom to push the hydraulic master cylinder.

 

The 68 prefix indicates 1936 first usage. I don't know how long it was used.

 

Thanks very much, guys. I will start looking for the one I need.
