Vintage New Old Stock RCA no.154 beat-frequency oscillator US Army Signal Corps

Description

This is a RCA no. 154 Beat Frequency Oscillator from surplus New Old Stock US Army Signal Corps.  I took it out of the wooden shipping crate and removed all the old packaging and desiccants.
This item comes with the original manual and a box of replacement parts.
This item has some rub marks from packaging, but other wise looks awesome.
I never plugged this item in, it is untested.
Ships to continental USA only.  I do not ship outside the US, sorry.
Item ships FedEx.
