Gas bottles vary over Europe, that is reality. Your best option as you need a new fitting would be to fit a bulkhead regulator then have appropriate pigtails for the gas bottles you use.

A single pigtail terminating in a 21.8LH butane nut plus separate cylinder adapters each with a 21.8LH connection is the neater solution and means having only one pigtail to replace when it expires. The adapters are available for every known cylinder fitment.
