Guys,
You're right. I think the same happened to me that happened to Colin. When you go searching on Google maps the address doesn't change from the first search made. In other words I started my two searches from the sites that Colin had provided. When I found Lahr and Bad-Soellingen the addresses had not changed so I just inadvertently repeated the sites that Colin had provided.
Please try this one for Lahr:
