NOS Panhead and early Shovelhead 24 " cigar muffler.  This is an early issue muffler because it does not have the date code that later production mufflers would have,  (example: 281 would be manufactured in February of 1981).  Definitely NOS a few minor scuffs here and there and possibly an 1/8 inch ding of two.  Chrome is awesome with a couple of factory blemishes where the end caps are spot welded on. A truly rare and beautiful muffler that is over 60 years old.
