This example is just one of two known for the variety!  The other example is in a private collection which is not expected to be sold for decades.  Thus, if you don't want to wait around hoping another example of this variety appears in the next decade, this is your chance to acquire a rare variety from a large family of counterfeit CBHs.
 
As you can see, this example was once holed, and then someone apparently just wanted to carve out an entire rectangular section on the right side.  No, it's not the sexiest example out there.  But if you need to fill this hole in your Pointed Wing family collection, then this piece may be for you!
