Perhaps I should post a couple of pictures to see if your interest remains:
As you can see it is a not very accurate replica which was modified by the wheel of the large truck which ran over it. The dog bone arms have been bent down and twisted sideways removing the chrome from the places where it bent. I had rather thought of it as a spare for people like me who seem to loose them. However if it can be put to use so much the better. The underside is non standard but it fits the neck ok and does its job well, IF you remember to tighten it!
If the pictures have not put you off, you can have it for £10 plus postage.
