Heres the link for the last 3456A being sold: https://www.ebay.com/itm/254103264737
Already looked at that ... maybe 15 minutes ago.
Every Home deserves a good solid Anchor - Do it and expand the area at the risk of a pan to the back of the head
.... if only one episode of a pan to the back of the head would do it.
Unfortunately, I would get "the look" plus a few other not-so-subtle hints over an indeterminate period - as well as pointing to a couple of maintenance jobs around the house that are have been waiting for me.

UM...Id let you have it for $200 Brumby. Shipping isn't important as I already have a box for you headed that way.
Even if you offered it for $50, I'd have to decline. As I said, it's more meter than I really have a need for - and I am being very hard on myself with new acquisitions.
I know, I know - that's not very TEA of me.
As I said, it's more meter than I really have a need for ....
I bet I'm going to withdraw that statement when I pull out the 24 bit ADC dev board I have sitting on my shelf.....
But no, it would be a nightmare to fit into my restricted space. I only have a maximum 35cm depth to work with.

(*Thinks*)... but I might be able to add a cantilever shelf which would look curious, but would put things out of the way and accessible.....
No, NO, Stop Brumby. STOP!!
Oh, I'm going to hell..................
Please ... somebody
please buy that 3456A.
Oh - that is just so hard to even look at.
Oh ... I'm heading for a slippery slide into hell - and you want to change it into a cheese grater!
Nothing like fighting fire with IPA......
On a SAD NOTE: just pulled the rear panel from the 7704A, I got in this lot, and found we have a causality.
Hopefully the damage is just in the rear and I can find (or make) new PCBS to replace this shit...so SAD..what a great unit, just mistreated like this.
I suppose I can save and share the parts as well...definitely less of a headache that repairing it. So If you need 7704/7704A parts, I am your guy
Damn, that is some serious carnage. Why do people not take care of expensive stuff?
What do we think this guy is worth?
I would say "free" to any collector that has a similar unit in their TEA stash already, just pay shipping. Its too nice to keep as a decor piece, and truth be told, I wil never use it for anything other than fun/learning.
Donate it to a school science lab? Dump it on ebay under vintage science gear as it is nice condition
https://www.ebay.com/b/Other-Collectible-Vintage-Scientific-Equipment-1930-Now/414/bn_16564447?LH_TitleDesc=0 worth $50-100 maybe?
That 7704A is a shocker too
to the person who did that to it.

I'd clean it first. From what is visible it doesn't look like the traces have been eaten away so it may look a lot worse than it is.
I'd take the low resistance standard, and pay shipping. Will "complete the set"... :-P

I doubt that a school would know what to do with it, unless it is on the curriculum. At best it would remain at the back of a cupboard until a kid saw it - and then probably went "eurgh, ark stuff".
That low resistance standard looks to be part of a kelvin double bridge. Unfortunately possibly missing its ratio set. Yep , im correct.
Yep Bridge element. Back when I was a Boy ....
We actually did Bridge measurements in Year 10 Physics with similar gear in spite of having Digital meters available. Good background still today.

Cool! Thanks for finding the catalog page. Never seen one of these before.

Looking forward to seeing your setup.

It needs to stay stable enough to actually show it. I recently grabbed a load of test equipment and need to work through fixing it and installing it...
By set I meant I'm the guy who got the resistor standards and most of the inductors and capacitance standard too once I finish paying for them.
Yeah, I remember you got all the others. As for stability, it's OK. No lab is ever truly finished. At some point, it'd be great to see it all in its new "home."
Could this be the 2nd half of the Bridge setup? Hard to tell from the older magazine photos but this makes the most sense with what is here. Thank you VgKid and to everyone for the help.
No this one look complete. You connect a battery on the left and unknown resistor on the right.
Kosmic is correct , the 4285 is a self contained kelvin bridge. Just add a battery

Wow, for the age that thing is in mint condition. Museum piece maybe.
