It's at work. I don't have access to it as of yet, just going from info from another person. He said it boots to a black screen with apple support on it. So I'd assume it's one of the 3 versions in the link above (folder, stop or globe). I thought without the NAND modules it won't even power on?

I hope that helps and you can turn on Find My again on your Mac.
They certainly did sell modules, you may want to check again?
