The Silver Jacket
The Silver Jacket, an Australian publication ran from 1953-1955. The publisher wanted to print Greyfriars story but Richards was not allowed to use the characters as they were under copyright from Amalgamated Press. Instead 27 Carcroft stories were published, eight of them being reprints from Hutchinson's Pie, the rest being original.
