Best way to approach this particular pressuretrol pigtail (photos) for cleaning, etc?

Probably missing something, but this non-plumber doesn't see an obvious way to unscrew anything or rotate anywhere - completely - in this (Bryant Dunkirk boiler) configuration, and recall seeing here that disconnecting the screw-fastened pressuretrol plate is not recommended (so as not to disturb the mechanisms there).
Thanks.

Your going to have to do a little surgery.

Buy a new pigtail, a 1/4" x close brass nipple (or the shortest one you can get) and a 1/4" brass union.

Cut the old pigtail off at the tee, leave a couple of inches sticking out of the tee so you can get a wrench on it.

Put the new stuff in with the new nipple coming out of the tee, then the union then the pigtail.

A Hacksaw blade with some tape around it for a handle will cut that pigtail

yeah,
that installer did you no favors there,
unless you want to repipe the steel the the right, *NOT*
you will need to cut that pigtail out,
and repipe a new pigtail to a more servicable location,
a new nipple and a 90 up at the sightglass, a long nipple up, then a pigtail where you can spin it,
you may need to lengthen the wire,
while your piping, add a low pressure gage on a tee with the Ptrol,

You CUT right through the problem! Knew I was missing something...
Much thanks for the details. The option for a useful-range gauge would be a bonus - perhaps could even see if the pressuretrol is actually working near the visible settings.
(FWIW, the manufacturer's photo for that PSB model boiler shows the pressuretrol/pigtail in the same place.)

This is actually the manufacturer's problem. Obvious that they have never had to take one apart. This is common in everything assembled at most factories. They never have to deal with it in the real world.

The installer was just given limited parts to assemble, even though he should have known the future problem with maintenance.

Rotate the pigtail towards you. Unscrew the pressuretrol. Unscrew the pigtail.

That's a Burnham? Looks like a Dunkirk to me..................

Corrected original post as per @Steamhead (had started to type the initial B of Bryant, and brain/fingers went awry.)
And appreciate the additional comments.
