Since Jayne seems to have run out of rusty old bits of junk at her place, here is a mystery object from me for you to have a guess at what it does.
Jayne is too kind and gives hints. I don't.
Apart from this object and some curious oddities to be found in my bedside cupboard, I don't have any other mystery objects, so give this one time your all.
S'pose I better tell you the size. It is about 8 inches or 20 centimetres long. The reverse side is just a screw head and and the rest of an address, Hue, Viet Nam.
Answer Tuesday morning if no one has guessed by then.
