Tektronix T5640 CRT's for a Tektronix 564 Otubes Part #154-0410-00

Description

I was given some info that these o-tubes are for
Tektronix T5640 CRT's for a Tektronix 564 Oscilloscope.
Check to make sure they'll fill yours.
There is some water or moisture staining on the boxes.
These were stored in my friend's basement for decades.
If there's any issue with the tubes, I will refund your purchase in total.
I am told the last picture of the o-scope is the unit these CRTs will fit.
I'll trust your honesty.
