I do now know very much about this item at all, it is out of my area or expertise (the pictures will best describe the item). It could be a good collector\'s piece as well as useful tool I looked through the eye piece and everything looks good. Any information you have is greatly appreciated. The price is very reasonable so don\'t miss out. This is a consignment item and all sales are final so be sure of what you are offerding on. I combine shipping on multiple items.
