Hi Brooke,
The cards have to be impregnated with a fireproofing solution
or a mini bonfire may result.

Subject: Re: Design of Cards for Campbell Stokes Sunshine Recorder
Brooke, I have a C-S sunshine recorder with slots in the arms for insert cards;
the slots allow inserting the cards in two N-S positions. I have, I believe,
two types of cards to fit my slots. I don't remember what each card type is
meant for, however. The glass spherical ball is about 92 mm diameter.
One card is 35.9 mm wide with straight sides; the other card is 30.18 mm wide
with curved sides. Both cards have a blue face with white nomenclature;
printing on the back is in German.
If helpful, I could scan the cards.
