I do my own custom clearances.
I also got a Hot snot gun
I do my own custom clearances.Shipments that have declared value under ~ 75€ are exempt from customs fees, but not VAT free. And, the rules allow the import handler to charge a fee. The VAT goes to the tax authority, the handling fee to the shipper. And no, they can refuse you the right to handle customs processing.
Another pretty piece of glassware

Here's a teaser of mine. Pic shows a front panel removed from a piece of HP gear that arrived recently.
Who knows what that gear is, and why this is very cool?
That's an interesting google read. Is yours intended for a project, or curio collection purposes?
It's an HP3437A:

No idea what's cool about it - it has the nice bubble display and button that might be useful as spare parts for other HP instruments.
10^-16A.
I'll soon have an HP 746A HV Amplifier on its way to me, to join the 745A AC Calibrator that's currently waiting patiently in my triage/repair queue. More ballast for the house. Snagged a couple of NOS GenRad 874 connectors, too.

Congrats, that is a very rare unit. Please post some pics from the inside, never seen it.

Well spotted. Yes, it's the buttons. Specifically, that the buckling-spring switch bodies have NOT been heat-staked to the PCB. They are held in place only by the front metal plate. All three units I've bought are like that, so it was apparently manufacturing standard for the 3437A.
I don't know of any other HP instrument with those switches still having their mounting stakes intact. Which means the HP3437A is the only source of replacement switches that I know of.
Are there any other HP instruments using the same button-switch mounting scheme?
It would be good to find something that:
* Has a lot of buttons,
* Is fairly cheap and common on ebay,
* Is relatively light so shipping doesn't cost a fortune.
* Is really obsolete and useless, so stripping it isn't painful. The 3437A is quite a nice instrument.
Ideally I wish I'd find a box full of just those front panels, for cheap. Like that's going to happen. ...
Not exactly bought, more a pre-emptive dumpster dive. As in: prevented this Meinberg LANtime M300 from ending in the recycling stack. This unit takes time reference information from the VLF transmitter (77kHz) DCF77 run by the Physikalisch Technische Bundesanstalt (~= NBS for you in the US) in Germany.
It serves as an NTP server but also produces a 10MHz and a PPS signal. DCF77 is of course driven by multiple atomic clocks. Signal is receivable about 1500km from the transmitter site (IIRC).
Top notch German build quality ❤️
Today I received a new meter, Brymen 867s. Actually purchased it May 24 from TME in Poland. Took only three days to get to California (!) That's pretty good timing. Plus I got to follow my meter on a fun international trip thanks to fedex updates... hey, my meter is in Warsaw... now it's in CDG, ah, Paris in May. On to Stanstead, then Indianapolis...

I'm 1200 km from the Langwellensender, and even with very cheap clocks we can receive the signal. I've got the same mainframe but with a GPS receiver in. Having a 10MHz signal on-tap is a force multiplier for every lab. Exact time is also good.
