Oscilloscope Part

Description

FOR PARTS OR NOT WORKING. I've never used it or tested it. I'm selling it as untested and non-working, for parts or repair. It has scratches, blemishes, flaws, imperfections, etc. It's missing the outer casing and probably other parts and pieces as well so I'm selling it as incomplete. It's dirty and could use some cleaning.
When I move it around I can hear some loose debris moving around inside the main glass tube (CRT tube?) in the middle - so something may be damaged or broken.
