Thor missiles
The pictures are very relevant to the thread and is extremely interesting. This is a Thor Trailer-Mounted Launching Coutdown Group, part of the control system on the launch pad, serial etc. is entirely correct. Is it still there? if so please do not destroy it!
I have the complete Thor manual and will post a diagram from it showing the trailer. The part number is a revised 1962 code. My book lists the earlier version, AN/MSA-21.
