What is the glass rod for?
A: Delay Line - this is a radar calibration device
|The rod looks like glass - might be quartz but it is awful big for that! The "socket" has a single lead that goes to a spring-loaded metallic contact to the center of the rod's base. The top of the rod is spring loaded too. The base of the rod has a ceramic(?) "button" that measures infinite ohms between the silver coated outside ring (ground) and the center contact.|

|Strange cover for Teletype M19 - Q: what is it for?|
|A: Ken W7EKB says -
"You have one photo of a "strange cover" for an M-19. I had an exact copy of that at one time. It contained a Model 14 or 15 (?) TTY plus a power supply and a tape punch. It was a "console" setup. The cover is spring-loaded to enable it to be lifted easily. Mine came from the FAA station in Missoula, Montana while I lived there."
