After a tip off, I bought the attached envelope on ebay:
The envelope is of interest to me because it was addressed to "the Lady" , Mrs Stuart Murray, who kept the Calling Book.
The envelope, perhaps, is also of interest to collectors because of the route it took to reach Hoopers Hill in New Milton:
1. on the front the postage stamp of Edward VII is stamped Fareham Ja 7 1904
2. On the back is a stamp that appears to read Warsash on Ja 7 1904 and
the stamp of the Brockenhurst Railway Sub Office (R.S.O.) was added on Ja 8 1904
The Railway Sub Offices were disbanded in 1905:
Railway Sub Offices (R.S.O.)
Postscript
The envelope was hand-delivered by the seller, who lived nearby in New Milton, and saved the envelope from the owners of Hoopers Hill putting it on the bonfire!
What were the chances (of the envelope reaching me)!

Interestingly, in 2017 I was offered a condolence envelope from Cambridge addressed to the daughter Ruby at Hoopers Hill, New Milton and dated May 4 1908:
The back of the envelope indicates that the envelope was received at Brockenhurst Railway Sub Office postmark May 5 1908.
