Default Help: horn relay interchange/test

I was wondering if anyone here might be able to help me out.

I am preparing for doing a table at a swap meet next weekend, and I have a horn relay here;
At a glance it's NOS, but the box is open;
I cannot be completely sure if this is unused (again the box is open), and there appears to be weathering on it, but the contacts look unset - while the tin ends on the container have zero weathering on them.

The part number on the container is 1116781

I did just check, and it isn't applicable to my Fireibrd according to my November 1974 printing master parts catalogue, but maybe it was superseded by another number which makes it interchange!?

Can someone also offer a means for me to test it if it's good?

I can see a sealed one recently sold on eBay for $150usd plus shipping, so I figure it's worth looking into this one.
