Oh sorry, i thought that you were looking for a battle axe directly associated with the Longobards. If you are just looking for designs of migration-period long bearded axes i found this very nice example associated with the Franks:

Edit: I just discovered that i can link to categories within the myseum site. All these axes are asssociated the the migration period:
