Yes, you are correct. That is the emblem from the Ford factory in Köln, Germany.
To decipher the part number on the side of your part, here is what the numbers mean:
G38T - 9425
G = Made in Germany
3 = 1943 start of production
8 = 50 hp, 4 cylinder, 3,2 litre engine (initially produced for this engine)
T = truck (Lastwagen)
9425 = generic Ford part number for a four cylinder intake manifold
The above is based on an original booklet I have which tells how to decode the Ford engine/parts numbers.
Here is a photo from the 1948 German Ford truck brochure which shows an example engine on which your intake manifold was used (starting in 1943):
Hope that helps,
