Price would be the only "deal breaker". 14's are nice SWs and if the overall condition were A-OK and mechanicals checked out, I'd be proud to add it to the stable I do believe.
Only if I was looking for a pristine collector example. For a nice shooter gun, I would shim the hammer to center it up to make sure it doesn't drag and affect ignition. If I was selling, I would make full disclosure; If buying I would discount it a little to cover the work. If the rest of the gun looks like the cylinder, that's a nice one.
