I would suggest that this is a 1.4x focal length converter. Your comment that there is no form of mount or attachment threads is somewhat of a puzzle, unless the thing was inserted into the barrel of the lens it was paired with. The idea of convertible lenses is nearly as old as photography itself You can buy a modern form of this converter for the Rollei 6000 series auto-focus and it ain't cheap. |
