A bit of a long shot, I'm after a few issues of Jag from the end of its run around Feb/March 1969.
Jag was an odd comic, tabloid, 16 pages with a wide mix of content, from humour to Sci Fi.
It had excellent production, featuring art from people like Joe Colquhoun, Jesús Balsco and Eric Bradbury. And yes its one specific story I'm after :P PM me if you can help!
