Mystery Oboe Gouging Machine #1

We don't know anything about this oboe gouger or who made it!  It has no discernible markings except that the blade is marked "11mm" and the number 4 is marked in black marker on the underside. 

We suspect that it was made by Kal Opperman but we are not sure.  It is mounted to a board and all parts move smoothly.   It appears complete and undamaged.  We really like the feel of the detachable handle that sticks out of the top.  

The blade is undamaged and seems reasonably sharp.   

This machine is being sold as-is.  We will not be servicing the machine or checking the gouge before shipping.
