That little Tek is rare and expensive. All Mini-Tek are expensive, also today. Collectors want to have them
What is the system on the far left center?
Looks like a Rhode & Schwarz Polyscope III

Has a frequency sweep generator inside and plots frequency vs amplitude of DUT (amplifier, filter etc)
But what is that strange connector on the bottom??
Thanks for the links. Looks like the same system. I like it.
About phosphors.
Tek made self the CRTs, so it was possible to order some sorts of phosphor with various colors and delay time.
The common phosphor of the most oldies is the bluegreen type P2 (see the 555 restoration). The delay time is around a half second.
Later it was changed to the type P31 grass green (see the 5403), it was the same but more resistant for burn in.
Specials: For using the polaroid cameras was the fast blue type P11 the best. You see that here in the subject on my Tek551 and on the 7844.
The most amazing type may be the P7. It is a dual coating with a fast light blue and a very long delaying greenyellow. I have a triple nickel with this dual color outfit, see here
Thanks Martin.M this post make me feel so small, there is so much we can learn from the past...
a poor 5403 (the same then 5103 but 60MHz and readout, graticule illum) fallen on the nose?
I found him in the bay "defect"
Right, that's it, the wife's just walked out on me.

More room for vintage scopes.
The cleaning of Tek Covers
You need:
A spraybottle windows cleaning fluid (this sort I have tested to be electric neutral),
a old machine brush, very fine, material = "Messing" ( CuZn40 )
2 dry textils, natural baumwolle
if you are interested, or you want to learn or repair an Tek Oldie, simply use my homepage and register there in the little FORUM.
There ist the headquarter of the german Tek-Oldies friends (a lot of english there, the world have found us).

That is a R+S Polyskop III SWOB, yes
this one is full extendet, there are 12 oscillators in the bank. Each of them is build with a very fine sweep controlled Low pass filter to provide a clean wave without any harmonics and with a constant amplitude.
There is a crystal controlled marker generator also.
The monitor top have slots and provides simultan 4 channels. In my SWOB are plugins:

I found him in the bay "defect"I can plainly see the Telequipment heritage on your 5403.
It's form is very similar to the D83, large CRT, mainframe controls at top right, plugins.
I'd go as far to say it's a Telequipment with Tek badging.

Hey, almost exactly the same as I use for HP & Tek crinkle-finish cases. Except I use a slightly coarser brass wire brush.
But what I want to know, is any method to clean in tangles of delicate components? Other than just slogging away with little bits of cloth held in fine forceps? Which I find exceeds my patience, so generally I just use a compressed air gun and overall brushing with a small paintbrush, dry.
Perhaps something like a miniature powered rotating feather duster might be good, but I didn't get around to improvising something like that yet.

I'd go as far to say it's a Telequipment with Tek badging.I thought it was the other way around. A few Telequipment scopes, like the D83, looked like a Tektronix scope had been rebadged. The real Telequipment scopes had a completely different style, mostly with wide horizontal plugins.
