I believe that is one of the "nicknames" of this appliance.
It is an armoured train built by Ansaldo for use in Jugoslavia. This one had a Breda 24/65 AA gun and up to 8 machine guns, 4 per side.
Regarding your earlier comment about trucks and now trains, I wonder, in all seriousness, if it is not time to again visit the question of splitting up this quiz into a strictly armoured and /or combat vehicle section and one for soft skins such as cars/trucks/trailers/horsedrawn equipment etc.
I can't tell you how much I appreciate you, Markus and many others putting up with my posting of 95% softskin questions, since that is my area of research, on a thread that should cover more than that, particularly combat vehicles which is such a huge field in itself.
I suppose the counterpoint is that we all learn more about each other's disciplines but I do notice it ends up in sometimes a long run of one or the other type of subject matter which may discourage others from jumping in.
Recently, it has been so that 4 or 5 members are doing the majority of the postings on this thread.
Not trying to cause problems, just asking.
Over to you Amigo.
