Holbay thanks for coming back to me, i had given up on this post due to little boys that know nothing .You know the type who like to make fun of every thing possible.
I dont know why it would be in my car W124 260E just under the arm rest . At the time i thought it was a part from inside the rest but after looking inside i dont think it is. I have had the car some years now and for this to just show up is uncanny .It was found as i was fitting a new seat cover.
It is like it in some ways - one for the road . Other than the open end part has these loops ..And i dont know why it would be in my car .Unless the mot chap had it in his pocket, i dont know. No one but my self , and the war depot [wife] have been in it .
