Temptation to break NC

Okay, so xN emailed me a cryptic email earlier this month to say she has "something for me" and is moving far far away (THANK GOD) and having yard sale, yaddah, yaddah.

Some mystery item. Well I figured out what the item is, but I didn't want it enough to break over 1 year NC. A piece of artwork that I was very fond of.
Well, it appears she is also selling cameras. I gave her a family heirloom, an antique camera worth hundreds of dollars.
The money means nothing to me.

So you are wondering what I am getting at.
I think she has listed this camera on Craigslist, I am 99% sure it is my late Grandfather's vintage camera (mint condition I might add) It meant alot to me, my Mother gave it to me and when I gave it to Cruella I believed I was going to be spending the rest of my life with her. She told me we were going to be married. (sound familiar?)

I am tempted to respond to the add posing as potential buyer. (OF MY OWN CAMERA)
To satisfy my intution, and to tell her she has sunk to a new low selling other people's family heirlooms.
If she had any decency whatsoever, she would have returned this item to me a long time ago instead of trying to bait me with this other art piece.

This would be a mistake, no? Explain to me why this might be a bad idea, please!
I thought if I did do it, I would immediately close the email account I sent this from so she couldnt respond back.
