Steve Holland has padded out the data I had on the Robin Hood strips, which originally appeared in Swift. He points out that the reprints in Treasure were in fact from #197 - 261 (22/10/66 - 13/01/68). The later reprints in Storyland (new to Steve - a miracle in itself!) still need complete data.
Steve adds: "the Treasure Robin Hood reprint [...] was abridged and bowdlerised in various places. It also dropped two episodes" which explains the discrepancy with Treasure only having 65 episodes and the original running for 67 through the two titles Robin Hood and his Merry Men and then Robin Hood and Maid Marian. Thanks Steve.
