Grip for olympus om

Is anyone aware of any grips made for olympus OM cameras similar to the Leica M grip??

There was an accessory grip called the "Camera Grip1" and it can be used with the OM-2S Program, OM-3, OM-4, OM-4T and OM-3Ti.

I recently saw where a fellow attached his Bessa grip to an OM and it worked out quite nicely. Not as elegant as the official OM grip but then again OM Camera Grip 1 are nearly impossible to find.
