Overbore
			 
			 
			
		
		
		
			
			Thank you Drew. That is the kind of information I was looking for. Actual bore measurements of SBTs to try to understand how many might be overbored.  
 
Just trying to understand if it might have been something Parker did as a standard offering. 
 
And thank you Harry for stating the obvious.
