1.5-2m price: Help me identify this guitar/signatures

So my uncle gave me this guitar, back from when he was a youngster.
Hes from 64. And back when he turned 18 he went on a roadtrip, he ended up becomming a roadie for couple of bands for some time, and after some time ended up in Italy for some years.
Long story short, he remembers either getting gifted this guitar and signatured people he rode with, or it being his own (we have old pictures but i live in spain right now so i dont have access).

But my uncle has since then passed and I do not remember the story behind it, now which bands/artists it was. (may have been small up and comming, may have held sentimential value to him), but he asked me to pass it on to someone that would appreciate it one day and find out who he had met. (he ended up having a drug abuse and major memory loss due to that, dont do hard drugs kids....)

I will pay 1.500.000 to the person that helps me find out what kind of guitar it is: info on the guitar, could it had been used during said artists performance, history, details. @Jebediah Jalalai thank you. 
I will pay 2.000.000 to the person finding out: signatures (are they the real once for sure) anyone with specialty in music/signatures?

Dont know if any of the stories or signatures are legit, or true. But i myself cannot recogize them. And it does not really matter, it was one of his wishes. - But the guitar has been in our family since his return in the 2000'. 

So far what i got is from the signatures is:
Ronnie Wood who played with Rolling Stones in the 80s which would fit.
Maybe Mick Jagger on the Far right?
Keith Richards maybe.
And Charlie Watts.

It’s The Rolling Stones formation from 1975 to 1985 - It lacks Bill Wyman and Ian Stewart, though Ian Stewart was apparently not considered an official member, more like an ‘extra’.

Any aditional information to provide me with some clarity would be greatly appreciated.
Great thanks if you help out.

A guitar that would fit together with the rolling stones dates would be a Squier JV (Japanese Vintage) Stratocaster. This is the first series Squier started producing and exporting back in 1982 or something. Here's a picture  https://smallaxemusic.com/products/1985-86-85-86-vintage-fender-squier-stratocaster-strat-made-in-japan?variant=2094623686665. I highly doubt that the guitar was used during any performance since Squier is fenders budget brand. I don't know any artists who uses Squier guitars. They are great guitars for beginners considering they are cheap and well made. However, after gaining experience a lot of people tend to buy a quality guitar from Fender or Gibson. 

The Rolling Stones signatures makes sense especially with the dates given and the dates that this guitar entered the market on.

Im pretty sure it was a guitar my uncle bought for himself to play/got it from the band as a gift and had it signed. 
He did end up buying a Gibson when he learned to play.

It is indeed the guitar you linked, i dont remember the yearmark, but theres a serial number, and ill be able to look it up from there and check the records.

Thank you. If the records adds up ill consider this as "enough proof" that the signatures are legit too - for now til i bring it to a specialist - which wont be in the near future. 

Let me know when you are online i will pay you 1.5m for the knowledge of the guitar.  paid
And 2m more if the records adds up with the serial number so the dates of the signatures would be legit.

@Jebediah Jalalai

thanks for the money bro!
