All this recent talk about these things has made me have another look at one that I have.
It is brand new, but I can't for the life of me fathom it out.
Listen carefully, and I will try and explain how it looks, if that doesn't work, I will post a pic.
5" long with a brass handle, top end has what I can only describe as a pigtail, like the letter S on its side.
From the centre of it is a spring loaded piece of wire which looks like a safety pin on one side, and a hook on the other end.
The spring wire is fixed, i,e it doesn't rotate on the stem.
Any help please before I throw it at Mrs T.
