Harmonica Locations? Sold one. Am I screwed?

[dropkickennedy]

Playing through I found a harmonica at the one gunslinger's hut and believe I fenced it without thinking. Later in the game, Sadie requests one and Arthur says that he did find one before, but will need to keep an eye out for another. All the guides only show the gunslinger's hut as the location of the harmonica to complete her fetch request, but there has to be more out there, right? Or am I screwed and unable to complete this fetch quest? Any insight would help.

I haven't had this happen. But maybe try and go back to where you hocked it and see if you can't buy it back

I was in the same predicament until about 10mins ago.
