These are new recording paper for a Campbell Stokes sunshine duration recorder. The cards are made by Casella London part number 6732 for use between March 1 to April 11, and September 14 to October 14 in both northern and southern hemispheres.

All are packs of 30 cards except 1 pack containing only 26 new cards plus two more cards that were supposedly used but don’t show any burn marks. The last pack sold will be the one with 26 new cards and two “used”.

I combine shipping if buying more than one set.

Please ask questions before bidding or buying. Payments within 48 hours. Contact me with any issues. Feedback given after it is received. Thanks!
