[GreenKeys] More on the mystery picture I posted 2 weeks ago.

[Richard Knoppow]

     The ones in the pictures look like they are wood. Some 
broadcast plants I worked in used Bakelite blocks of the same 
type. We called them Christmas tree blocks. The original plant 
had been constructed with soldered joints (c.1950). The most 
useful tool I had for them was a couple of wooden chop sticks. 
The newer part of the plant used punch down terminals on what we 
called 66 blocks. You could punch in the wires with pliers but 
there was a correct tool for it. Also, those blocks were designed 
for solid wire. They would work for stranded wire but not as 
reliably.
