Torch on a Hook (Harrogate HG1)

Small, handy torch with a fold-out, fold-away hook.
Offering on behalf of a friend following a family house clearance.
It isn't coming on when I press the switch, but I can't manage to open it to check or change the battery. Would anyone like to give it a whirl? Worth a try as long as you are local for collection. Not worth a trek, obviously. I am in the town centre, close to Asda.
