Ju88, the back of your eagle is typical of the wehog eagles that I have inspected. A poor cast nub that shows that there never was the 2 1/2- 3 inch cone/stud that all others were found with or evidence that they at least started out this way.
Your eagle only has 2, approximate 1/4 inch holes drilled through the wings with perhaps a metric 6-8 mm bolt inserted. The boss at the bottom of the swastika was never even drilled. I ask the question, other than the sheet rock in your living room, what other possible application would this eagle be able to hold fast to ? If a legit period eagle were in fact cast that way, the uses would be entirely limited, and not like the others that started out with a hefty cone stud and could be cut down for any application. The Wehog that you show wouldn't make sense to manufacture in this fashion, because it would lend itself so limitedly.
Now take your hand and run it around the circle that the swastika and wreath are in. I'm willing to bet that the wreath is so jagged that it would cut your hand with just a little amount of pressure. Every railroad eagle that I've ever owned or inspected, is nice and smooth and hand finished in this wreath area. And as a matter of fact, all of the edges on these birds are hand filed and deburred.
Lastly,take a look at the top edges of the wings on that Wehog. I bet that there are file marks that are in the casting, and not something that was done to finish the bird after it was cast. Another indication that the piece is cast from a mold that used a real period Wehog to make the reproduction.
If in the end you're still not convinced, send your eagle directly to Tommy, as he is buying all Wehog eagles for top $$$
