We have found the records on Ancestry for a F Minns Driver who would be a good candidate for the old man

His regimental number is 75894.
However, he appears to have been reported as dead of wounds in the following places:
Name from the Royal Artillery South African Memorial Service Booklet
and
Royal Artillery Memorial, London
This conflicts with the attached document from Ancestry.com. The attached appears to show he was transferred to Army Reserve in 1903.
Would anyone be able to read this attached and see whether it appears that F Minns (right hand side of the document, 5th from top) was dead or actually discharged and in the army reserve at a private address.
The service numbers are the same.
