Here is a Caille antique outboard motor exhaust manifold and muffler.  This came from a Liberty single. We never had the engine it

belonged to so can't be sure of the year.  Check out Jack Craibs' Caille website for identification. Has the original snout and the brass plate shutter which is usually missing on these parts. These mufflers are some times removed or cut off by previous owners in an effort to get easier starting.  Look at the photos and email with questions.  Thanks for looking.
