Q: What is this Russian equipment ?- includes a paper tape printer - Model ARGON-B

A: Strip printer for radioteletype interception - see info here

ARGON-5 is a variable-speed teletype printing unit used in intercepting radio-teletype messages. It is fed by the ARGON-4 demodulator, presumably fed by a radio receiver. The “SETTING” dial allows the operator to adjust the bit length in milliseconds. Assuming that the intercepted traffic was encrypted, it seems odd that this is just a printer and not punching tape for later analysis, but what do I know…. 
It was evidently used in this mobile radio intercept unit

Q: What are the two black units to the left of the Teletype gear? 1959 USS Pyro AE-24 
A: RBO-2 receivers with the Escutcheon Covers in place. These covers were added 
after the RBO-1 contract to reduce RFI to the receiver.

Crank for ??

Solved! - Ken VE4HMQ says:
"Used on Teletype M14 tape printers or TRP's to adjust the range finder thru the front of the printer thru an access hole in the cover...
This is a Teletype Corp'n modification kit, it enables Wire Chiefs to adjust the range while testing circuits...
It is a geared linkage set up, and the crank is differently angled to clear the keytops while turning it..."

What is this module?

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?
m19-mys.JPG (465459 bytes) 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."
