The way the arms are out in an awkward pose, I reckon it's a shop window dummy, probs with a scary mask to scare people for a laugh. I'd like to get my hands on a shop window dummy, and put it somewhere people would notice, such as hanging off a cliff at the pass of Glen Coe, where all the cars slow down to look at the waterfall. I could dress it like a climber, tangle it on old rope and encase it in ice. I'm sure the mountain rescue team wouldn't mind, after all, Hamish MacInnes spent a day throwing dummies into the air to fall into the river, during the filming of Monty Python and The Holy Grail, when the unfortunate knights who failed to answer the questions three were cast into the Gorge of Eternal Peril (aka the River Coe).
