Folder with some Berliner documentation ca. 1900

In a small lot of telephone documents that I bought a while ago I found a folder with some information on Berliner telephones.
I scanned it and made a pdf of it.

Click on the picture below to open it.
It contains 14 pages of mostly pictures of telephones, parts of it and some technical drawings.
