Rare AN/USM-339 US Military Contract Water and Weather Proof Oscilloscope LOOK!

Description

This vintage Hewlett Packard Waterproof Oscilloscope model AN/USM-339. Is being SOLD AS IS AS FOUND. Proudly made in the U.S.A. The unit does power up showing a green spot on screen. I can move the spot up and down and left and right. Have NO WAY to further test. Case is okay with scuffs. Lid seals well and is a little hard to get loose. Comes with extra leads.
Would be a good purchase to restore or display.
