I knew that there was one area of Germany that had a strong gun making tradition. I am thinking of doing a UTube comparing the Haenel 28 to the Tell 3. In looking up where each gun was made I found that Suhl (Haenel) and Zella-Mehlis (Tell 3) are less than 5 miles apart. During WW2, 10 different weapons manufacturers in the two towns were combined into a coordinated effort for production, probably not air pistols.
