Some months back I went to pay a visit to my Mum in my home country and managed to find this kit:

This is presumably from the early 90s or late 80s, I was supposed to build it with my Father but for whatever reason I we didn't.
Now I want to assemble it at the best of my capacity but I'm afraid that the decals might be old and therefore not good. Of course an option is to find other decals but I'd really like to assemble the kit as it was.
Long story short, the question is: Is there a way to understand the quality of the decals before applying them?
Thanks,
Antonio
