Textronix round o-tube CRT for models 541, 545 Part #154-0098-00

Description

According to barrytech.com, this o-tube is a round unit for
Tektronix 541 or 545 Oscilloscopes.
Check to make sure they'll fill yours.
There is some water or moisture staining on the boxes but it appears just surface as the cardboard is just as intact.
If there's any issue with the o-tube, I will refund your purchase in total.
I am told the last picture(s) of the o-scope is the unit these CRTs will fit.
I'll trust your honesty.
