Thank-you TLD and Nanook. It's still a bit blurry though! I remember taking this when I was going through a slides phase, although as indicated I cannot remember the exact year (but I did not get to Edinburgh from around 1978 to 1983).
Would anyone one know whereabouts in the zoo they were kept, at a guess i would have said one of the paddocks at the top of the hill.
Definitely worth posting, thank you @Parrotsandrew.
