The rims and cups in the Standard and the "300" Series cornet 
	line are identical to those in the trumpet line with the same number. 
	For example, a 4/7C trumpet mouthpiece has the identical rim and cup 
	as a 4/7C cornet mouthpiece. The cornet mouthpieces have a larger throat 
	(#26), which allows more air through the instrument for a darker, richer 
	cornet sound. The No. 0 to No. 15 are also offered with an "S" (symphonic)
	backbore.

All other Marcinkiewicz cornet models are special orders and are non-cancelable and non-returnable.
