the German and Itallian Tonkas had an extra internal tank in the fin
AGS man, yes sorry your information is incorrect. It was our (British) Tornados that had the Fin Tank and it held 440Kg of fuel……made all the difference. Had a few problems with them over the years, but to my knowledge they are all back in service now.
A new term was introduced with the Tornado when you had too much to drink, it was called “Fin F”
