PCB identification

[sherbie]

Hi all, this is a bit of a long shot, but does anyone have any idea what this PCB might be for?

I have a few of them, packed in padded boxes and sealed. The NIN suggests it's a circuit board for some sort of military equipment, but other than that I don't have a clue. Not sure if it will have some sort of value to the right person, or if it all just wants sending for scrap.

I presume the shiny metal surface is just some cheap tin/solder covering? Really appreciate any help, and if you don't know what it is but know someone who might be able to tell me, I'd be really grateful if you could give me a shove in the right direction!

I believe the surface is covered with solder, yes.
What does NIN stand for?
