Well, two 3478A's went for ~£120 each today, had a cheeky £45 opening bid on one of them, but it wasn't to be... never mind, I have more than enough bench DMMs anyway...
Been trawling ebay for some decent verniers, and my conclusions are (a) there's a lot of garbage out there, (b) there's quite a few fake Mitutoyos out there, and (c) most of the good stuff is overpriced.
I'm reduced to making speculative purchases of (probably) fake Mitutoyos and hopeful bids on quality used ones.
This listing is probably for the most loaded PNA-X ever in the history of eBay:

Having been stung by cheap digital calipers (you don't really want vernier calipers do you ) I bough some from ARC Eurotrade

and have been very pleased with them.

While I was googling to see what "mirum uacuatur" meant...
I am reading about indoor air quality lately:
- Temperature comfort
- Humidity comfort
- Filtration
- Fresh air circulation
Once you have addressed those 4 points you are good to go.
I also personally think that the humidity comfort is one of the most neglected one in homes nowadays.
Finally! I was able to get a device from Norma's 900 Series (last series of NORMA-branded DMMs):
NORMA NORMAMETER 940
Almost fully working, only temperature reads nonsense. Looks as if a mechanic used it to rub an exhaust pipe clean by the amount of black dirt. Voltage and resistance measurement almost completely identical to BM789, once again an old device with flawless calibration after decades.
Should I do a separate Thread for Presentation, Images and Teardown after getting all that black surface patina off?

Yeah, but he was a southerner, which barely counts, practically a foreigner.

If you can wait awhile, keep an eye open either Aldi or Lidl stores to publish their weekly special buy list, a couple of times a year they both get in stock some verniers that while not top drawer ones, they are considering the price pretty dammed good. They are same units as both Med and Mnem have but with a different brand name on them, and they are certainly upto the job for the hobbiest.
The question here is can we trust a man who spells hobbyist "hobbiest" to be actually talking about "verniers" at Lidl and Aldi and not about "veneers".
I am now going to go on and make the most massive. most embarrassing spelling mistakes in every other message I post this week.

It triggered my inner spelling/grammar nazi as well, but as I'm alreadynotoriouswell known for it "irl" I choose not to rise to it "online".
Besides, if I did, I wouldn't have time for anything else. Though on this one occasion... "I am now going to go on and make the most (double space) massive.(period/full stop instead of a comma) most embarrassing spelling mistakes in every other message I post this week."
EDITED for formatting.

Closer to being a Monkey Strangler than a monkey.
No reason in the world he can't make a little L-tab from a scrap of brass or steel and solder it to the back of the contact leaf. As for the silver contacts themselves, if they really are that crusty, while he has the switch out to fix that tab a few passes with some 1500-grit emery film will bring them back.
mnem
No need to make the L tab, I kept the one that broke off ! It's just that I have no experience and gear to do "micro" soldering, or any soldering really ! Well I mean other than electronic stuff o course...
The strip broke just one mm from the contacting element, so not much room for mistakes or I would melt the contact...
Hey... I am thinking, to get around this... maybe I could just add a supporting strip beneath the broken strip ? Then maybe just glue it all together, simple as that ?! The forces it would endure are so light, and that switch would be operated so few times in his retirement now, might just do the trick...
Now what "glue" would be best for metal to metal, I don't know... super glue would probably do it I guess, parts are so small and light, but if there is something better, tailor made for metal, would rather prefer that...
Or yeah, spot weld the broken tab to the supporting strip, then spot weld the latter to what's left of the strip. This way I can spot weld away from the contacting element and therefore no risk of damaging it with heat.
Would have to be a precision spot welder then, with a fine tip... if anybody knows about these things as has a few links they could provide, I am all ears !

Clearly you were never a teenager then!
For that flat panel, to get a nice finish I would get it laser cut. No as expensive as you would think. In UK there are online sellers were you just enter a sketch and they quote and send you a finished panel. Some have pre-anodised stock to cut.
For the printing I'd use the toner transfer paper intended for PCB resist applications. Print on to it with a laser printer (colour printer for red of course). Then just iron it on like a PCB resist. You might want to put clear spray varnish over the top. If you do make sure the first couple of coats are light or the toner will dissolve.
