I think that most enthusiasts I know have always used aftermarket coolers. Have you tried looking at CPUs on sites like cnet or newegg? They are the best retailers when looking for graphics card specs (alongside reviews etc, when I can't find the original manufacturer specs on the wayback machine), so they may have that info. They seem to never delete old pages.

Late stock cooler had copper core and radiator fins were arranged in circle around it. Original was just plain aluminum radiator with variable Intel fans attached.

Yep, but there are still a lot of different models, for example:

Round copper center with 4 main "arms" and smaller straight fins

Round copper center with thick fins in circle that get thinner and end up doubling up

Round copper center with thin fins in circles that don't get thinner and don't double up

And also the more "normal" full aluminium block with no copper core, which also has several variations in thikness and shapes

There is only one reference model mentioned in the Intel guidelines below here (but there may be more).

Here an interesting overview:

I suspect that the models with circular fins are later models as intel used that same design on their stock socket 775 coolers.

The best way to figure this out is probably looking at new old stock open box CPUs to see which coolers came in the box. Any collector with a good range of open box P4’s could do it.

Yes, and also the copper core of those circular ones are way bigger than the one in the 1st picture.

Here are 2 of them side by side

Round copper center with 4 main "arms" and smaller straight fins

That one was designed for middle-tier CPUs and has less weight and height. Usually was bundled with high RPM fans.

Round copper center with thick fins in circle that get thinner and end up doubling up

And that one was designed for top-tier CPUs and if fact was bundled with Pentium 4 Extreme.

Round copper center with thin fins in circles that don't get thinner and don't double up

From my understanding it's just earlier revision of cooler above.

Also twisted radial style heatsink for P4.

Cheers,

I also have a S478 P4 stock cooler with copper base plate and straight aluminium fins somewhere.

Maybe thinking of this one which came with my original boxed P4 3.067 GHz / 533MHz (SL6S5)

I think that's the one. Mine came with a 3.2GHz Northwood.

I think this is OPs best bet.

I've seen many of these stock HSFs but I never recorded what CPU was found beneath what stock HSF. But I do know that the stock HSFs became somewhat beefier as the CPUs became hotter and hotter. My guess is that especially Presshot motivated Intel to beef up its stock HSF design.
I'm reasonably sure that newer CPUs with a not top-high TDP could have gotten smaller HSFs. It's possible Intel used more than one design stock s478 HSF simultaneously.

EDIT: It may be possible that the stock HSF got an extra redesign with Intels introduction of BTX even though BTX (iirc) didn't affect s478 directly.
It could be quite the challenge to figure out which HSF came with which CPU without having access to boxed stock units. But tbf, Intel seemed to be redesigning its stock HSFs almost constantly at the time.

Are all stock S478 coolers made by Sanyo Denki btw?

NVM I think I was able to answer this question on my own.

The whole fan assembly is a bit different to the one PC Hoarder Patrol posted as well: larger fan blades and what I think is a thermistor to regulate fan speed based on air temperature.
The heatsink itself looks identical.

I have 3 versions of P4 stock coolers.
1) Horisontal ribs, no copper plate.

2) The "X" version.
3) The "Orb" version.
IIRC Northwoods were shopped with 1st and 2nd designs, Prescotts with 2nd and 3rd designs...
There is 1 trouble. 2nd and 3rd coolers can't cool my P4 3.2 E (D0 revision). The 1st cooler can.
