Cylinder head identification

[mcorrell]

I am trying to identify the cylinder head that is on my 1929 Model A. Several years ago my father had the cracked head replaced by a local Model A guru (now deceased ). My dad cannot remember if it was a used original or if it was aftermarket. To make matters worse there are no invoices for the parts or labor and the engine has been repainted since. There are several markings cast into the head. Can anyone tell me what to look for on an original Ford head?
