Patricia Cornwell matches the Openshaw letter to another from the same batch of paper, with an "A Pirie" watermark sent on 22nd November 1888
She also connects these with another letter with the same watermark sent on the same date, her suggesting Sickert had different batches of paper and wrote all three communications
A curious fact is that poster "Tempus Omnia Revelat" at Casebook believes writing in the Diary matches that of a certain postcard - also sent on 22nd November 1888!
Bit of a coincidence that - I'll look into this a bit further
