actually my post above was a delaying tactic to get the photo of mine ready.

3" dia. dial, box is just under 6 in. sq.

set up on the box, gnomon elevated to corect 52 degree angle, needle lock disengaged, feet adjusted to level device.

folded up, needle lock engaged to press needle up into glass to prevent it flopping about.

note the antique cheap plastic bubble level i found in a local DIY chain.

i note that atlantia''s pocket model also has a needle locking device that is engaged when the lid is closed. this lifts the needle off the pin and prevents damage to the bearing during travel.
