I think this one has a chance.
The 3 stud set up is correct and 24" birds are most common. The reverse set up dones not match the reference however so I would suggest you bounce this one off JR.
Why is it a fake? please elaborate...I, like Paul think it has a chance....regards, Ryan if you are going to condem an item to the scrap heap forum rules dictate that you must offer more of an explanation that you have thus far!
This appears to be a 35" wide eagle. They are harder to find. The reverse has a nice patina. The studs appear to be cut off. Appears authentic.
