There are again major differences in the 1938 Reichssieger
1. I Don't know the correct English word for it but the feather on his elbow is straight while it should bend out at the end (see pic).
2. Upper arm is shorter .
3. His schoulder is longer.
4. The cheek looks more like he's got a bigger back of his head (should be more towards his beak).
5. The eyes are lower and got a bigger upper head.
6. Angle of his mouth is steeper.
7. Shorter beak (should be like the other beaks) it looks more like an Aurich but again shorter.
8. Shorter neck and wider.
As i just saw the pictures of the catch i don't have a compare pic of that part.
But what i think is strange again on the 1938 is that it's a flatwire catch,never seen that before and in my files there is not flatwire catch to be found, only roundwire and a big catch block like on your 1939 Riechsieger.
The pin seems to be allot shorter (couldn't see very well),it should stick out about 8 to 10 mm.
Although i'm still not sure about the authenticity of the 1938. it could be another die and this is the only one i've seen like this.
Personally i would go for the 1939 Reichsieger it's a textbook example (wish i had the money for it

Maybe Raz can show his badge.
Hope it helps
