You know,, not knowing what it is may work to your advantage if you are going to put it on ebay !! That is how I would list it !! " Its for sale but havent a clue what it is" or something similar would probably get more views that putting the name of it would !! People have a natural curiosity and will click on it just to see what it looks like !! Someone out there may know and tell you what it is or may have a use for it without knowing its identity !!
