	76	Basic diameter minus 2 inches (2 inch correction does not apply to ( ) 9684 blade)
	63	Basic blade model
	D   	D or F denotes dimensional modification from original design
		B or K denotes deicing boots
	 	R when used denotes rounded tip for basic diameter
		S when used denotes square tip for basic diameter.*
		Any other character denotes minor change not affecting eligilibity
	3R   Number of inches cut off from basic diameter
		Q when used denotes special 1" x 90 deg. factory-bent tip for cutoff diameter
		R when used denotes sepicifically rounded tip for cutoff diameter
	     Any other character in this location denotes tip shape

*  Blades may incoporate either round or square tips, yet may not be markeed with an "R" or "S" in the blade model designation.  This character is used to distinguish between two or more tip shapes available at the same diameter.  Certain blades use "S" to denote shot peening of the blade exterior surface.
