Here you will find the short stories, authors unknown, published in the TV21 UK annuals in 1971/72. It seem's clear the author's didn't pay much attention to the outline they were given, or had defective hearing as they refer to the Spindrift as the "Spendthrift". That aside, they can still be classed as fanfiction, I suppose. If anyone knows who the writers are/were, please let me know and I'll credit accordingly.
