Might one ask for an unsanitzed version ? If this is against "company

If by "Plain" you mean "no fourth band", I thought that indicated
"20%", not "unspecified".

'Unspecified' would leave a rather wide margin for the resistor
manufacturer.
I used to joke about why there's no tolerance band on 'zero ohm jumpers'
(short-circuit shunts built with the same package outline as a resistor,
often used in instances where a board-stuffing machine needs to put
*something* in a hole where a resistor might have gone. Usually they
have one black band in place of the regular 'resistance value' bands).
But what's the tolerance on a zero ohm jumper if it measures 20
milliohms on an accurate low-resistance bridge? (divide overflow)
G, S, and P are, of course, Gold == 5%, Silver ==
10% and Plain ==
unspecified tolerance

There a plenty of jokles about 20% 0-ohm jumoers being cheaper than 10%
ones :-).
I believe the actual spec for a zero ohm jumper does give a maximum
resistance if it's installed with a particular lead length. Which makes
sense.

Zero ohm jumpers are a relatively modern idea. I've seen boards in
classic computers (some old HP stuff, for example) where options were
selected by soldered-in low-value resistors (10 ohm, 22 ohm, etc). A
shorting link would have been fine, I guess they used the resistors for
the same reason that zero-ohm jumpers are now used -- automatic
board-stuffing machines can insert them. Zero ohm jumpers didn't exist
back then.

Zero ohm jumpers are a relatively modern idea.
We use both zero ohm and infinity ohm (well, very large value) surface
mount resistors on space flight hardware. There are cases where you
are building tapped delays where you don't know which taps will be
used at the design stage. If you leave the unused taps disconnected,
quality control will assume a required part is missing and send it
back...
We also had a case where we had a imaging detector anode with infinity
ohm SMD resistors on one side and 0 ohm resistors on the other side.
The technician wasn't careful and we got it back with some resistors
swapped. The dead pixels confused us for a while before we figured it
out..
