<VV> Space Saver Spare for Early Model

[BBRT]

Pretty interesting. If it has been written up, Mike, it has been many years. 
I don't remember it. I think it would be a good tech tip for the Communique.
How about looking into the center hole issue for us? Not all of us have 
access to a Bridgeport..(yeah, I do).  :>)))
