I made a few tests!
It looks like mine is real "Future"!
The smell is right!
When it's dry it's very very thin and shine! Wow...
It resists perfectly to all the thinners for enamels
These are my results:
Future resistes to: humbrol enamel thinner, white spirit, zippo oil.
Does not resist to: tamiya acrilic thinner, tamiya lacquer thinner, alcohol95%, nitro paint thinner (that eat the plastic too...too powerful for everything).
Now I'm going to prepare your version of a "flat future" and "semigloss future" and I will put them in drop bottle for future use.
I don't remember the proportions of tamiya flat base and future.
I don't remember neither where you wrote them.
Can you plase remember me the good proportions for a semigloss and flat finish? Please!!!

PS OMG!! I see now that there was a thread specific for Future questions! I'm so sorry!
I didn't pay attention...I was in a hurry to write in this forum.
