Unknown crankset! Who has some information about "ales"?

Hello everybody!
I'm from germany and (sorry!!) I don't speak italian but I'm looking for some information about a unknown crankset from ales. I have this lightweight crankset with alloy "ales" screws. It looks like a crankset from Gian Robert but it has this stickers with that "a" on it.
Could it be that ales was the original manufacturer and gian robert only a customer from ales?

Thank you very much!

By the way, the total weight including the bottombracket screws is about 540 g


Here are some pictures

Thanks for your answer!

No, my ALAN frame has no ales decals or other things from ales. The frame is from a huge german bike shop called Brügelmann.
I'm very confused, that there is no Inormation about ales in the internet.
My hope is that here are some itilian users with more information about ales!

But at the moment it seems like ales has never been existed
