Hi,
Yes, always lucky when in an observatory :-)
With help from Eric at Uppsala University I have corrected the information.
All three observatories belongs to Kvistaberg's observatory. Tamm's observatory is the old at the summit. He had earlier a private observatory behind his villa. It's a photo of it in one of the links.
Here it's once again with updates:

More will come later.
