The ones that the OP has look totally legit and orig.
But I wouldn't be the least surprised if the someone started making new tools under names like the defunct Indestro (closed in early 90's). It's been happening lot on in other industries like in bicycle frame companies.
If there's a complicated, indirect path or lost connection to who owns the name, then they have been taken over and used for new items being made in Asia. They don't copy the old products but instead introduce new modern ones with a name that has heritage.
Having said that, Indestro was used up to the 90's so there's probably still an easy path to who owns the names rights in some lawyers filing cabinet so either it wont be used or someone bought the name cheap. Companies that went defunct in the 50's or earlier are better candidates for name use.
So rest assured, you have the real McCoy.
