Cutting vulcanised moulds book

I wonder if members can recommend a well illustrated book on lost
wax jewellery casting. In particular, one which covers vulcanised
mould cutting in detail. I already have my casting workshop set-up
and running, but I want to improve my mould cutting technique and
knowledge. I own “Murray Bovins book Centrifugal or Lost Wax Jewelry
Casting” but find some of the illustrations difficult to appreciate,
is there another book with better illustrations available please?
