The bunker desk phone 39 was used as a table model instead of the bunker phone.
Unlike the TF 38, this phone differs on the following points:

• The handset does not have a talk button
• The handset is connected directly to the telephone with the cable
• The FTF 39 was connected directly to the inner junction box of the bunker long distance cable without Beikasten

Full phone. Tested and works.
