It's bugging me now. I want to know what it is. Yeah, need closer, clearer pics from several angles.
What are those protrusions on the handle - a bolt and ... ?
Is there some sort of groove or shaping in the handle?
'Guide' - is that on the handle or on the metal plate attached to the glass bit? Are there any markings that might be associated with 'Guide'?
When you say the handle moves in all directions, do you mean it has a ball/socket join? Or is it more like a hinge (up and down only)?
Does it appear that there are two pieces of glass stuck to each side with nothing in between them, or is it just one solid lump of glass?
The black bit surrounding the glass (pic 2) - what is that made of? Or is it just part of the glass lump?
Is there a museum you could take it to or send pictures to?
