Since Paul Mauser died in 1914 and the battle in Remagen was in 1945, 30 years later, I guess that a holiday home with staff would have belonged to another Paul Mauser, perhaps to his nephew Paul Mauser II.
Great info. We should look into that. I was at the remains of the Remagen bridge 2 years ago.
I found this quote

The mansion we occupied that first night in Erpel is pictured in our 78th division memory book. We soon learned it was the home of Herr Mauser, the German munitions magnate. We remained there a day, allowing occupants to stay in the cellar. As we were leaving, Sergeant Titus told me the owner of the house wanted to speak to me and ushered in an old gentleman. The old man handed me a small package wrapped in white tissue paper and said in English, “I’m Mr. Mauser, owner of this house. I want to thank you for the way your men have treated my house. Please accept this as a token of my appreciation.” On opening the package, I was dumbfounded to find a brand-new .32 caliber Mauser pistol. I thanked Mr. Mauser and left, realizing only later that Germans under our control had to turn in all their guns. The pistol had no ammunition, but I managed to get some and carried it in my hip pocket until the end of combat. It was much handier for night use than my army carbine. Of course it was of little value in the daytime.
