Fields of Nephilim logo modified serif type

Anyone know what the attached font is called please? It is used by the band Fields Of The Nephilim.

Many Thanks


I suspect it is a modified font. I don't know what the pre-altered source is but somebody here should.

This is pre-digital by Vaughan Oliver, and although I have found the source for most of the type compositions on his iconic record sleeve designs, this is one I couldn't pinpoint.

Thanks for your help, I knew this wouldn't be easy...
