These are American companies, so their behavior is completely unpredictable,
except in that they'll take every opportunity to take your money. If they can
FedEx it to you and make an extra few dollars, they'll do that, methinks.
As for the 1" tapped spacers, one of our local surplus houses has them, though I
don't remember whether they have the 2x22x 0.156" edge connectors with the
solder tags right now. Nonetheless, I think they'd make the attempt to ship to
you, though I think it might work better for you if I did it, since I can claim
that it's a gift and of no economic value. What's the policy in Britain
regarding gifts of old hi-tech gear?
I have the spacers and may even have a 2x22x0.156 with solder tags down in the
"pit" somewhere. Perhaps I can find it. IIRC, I do have one that I used in
order to attach to a Digital Group video/cassette interface board some 20+ years
ago. Maybe that's the one I'm thinking of.

which
Do you need a PC-mount version or a wire-wrap?
Ideally solder-tag. The I/O connectors on the HP?421 are the card edges
of the option boards (Analogue mux, digital I/O) in the instrument. I
need to connect a cable to one of these boards. I can use anything, though.
I've made up a strain-relief bracket [1] so the cable is not likely to fall
off, not matter what sort of tags the edge connector has.
[1] I needed a couple of 1" long tapped spacers to fix the bracket to the
connector. I had a choice, either spend an hour in the garage with a
length of brass rod, parting off sections, facing the ends, drilling down
the centre and tapping, or spend a couple of hours going to the nearest
shop that might have had such items (but which probably didn't). Guess
which I did :-)

Not yet... Do those companies ship worldwide? We don't normally consider
them in the UK.
