A couple of weeks or so ago, there was a thread concerning the
painting of
stands for Stevenson screens.
I have just come across an old met office pamphlet entitled
'Instructions
for making thermometer screens of the Stevenson type', HMSO,
Revised in the
Meteorological Office, 1937.
In this it is stated that wooden stands should be creosoted for
the lowest
21 inches of the legs, and the rest painted white. Metal stands
should be
made of galvanised mild steel. There is no mention of painting
these.
If anyone would like a copy of the pamphlet, please e-mail me, and
I will
make a pdf copy.
Hope this is of some help.
Metal stand at Solent MRSC seems to conform to this specification,
it
is not painted white and seems to be just galvanised steel.

Ganvanised doesn't last for long in a maritime environment with
lashings of salt spray and high RH.
What do you do then - especially if like mine it is well and truly
embedded in concrete a foot or so below the turf?
I've just taken the opportunity of a beautiful day here on Fair Isle
to give my screen stand its annual chipping, wire brushing and two
coasts of grey Hammerite.
In 33 years I've got through three screens . . . but its still the
same stand!
