We can't get it on consoles you can only spawn the Crown with the PC console commands. The Ancient Falmer set can use the normal Elven Helmet if you want it for the full set perk (doesn't look half as good though).
Quote: yes the falmer crown can be found the problem multiple spawn locations around and in the forgotten vale keep searching
He's lying. On PC, the Unofficial Patch fixes it, but for you...
Sorry, mate. Console guys kinda get shafted sometimes.
