Nimrod,
Is this the one you are looking for, there are number of Horlick burials at Ruardean? If not, if you give the name I will check it out. This particular MI recording was by David Woolven of Newport, Gwent in 1989 (he has abbreviated some words and there is no detailed description of the memorial). I assume it is still standing as I believe there have been no clearances of memorials in this churchyard. No doubt it has deteriorated in the last 30 years!
