problematic too.

I assume the latter *will* be located outside!

... no doubt! But the problem comes with finding out what type of
collector is used - diameter of funnel - location relative to other
objects - representativeness to 'open ground' - was it put at ground
level (i.e. the rim *ground* level, or as for standard gauges now,
with the rim above the ground - or was it put on a roof - a common
arrangement at the time - if the latter, was the building it was put
on of a style that would significantly distort the rain 'envelope' ...
etc.

Unfortunately, it's not like I can email the observer to ask...
