I don't think NASA had the right to "give" the camera in the first place. Its government property right? If I were in-charge of fighter planes, I couldn't give parts of it away as going away gifts. If I did, I would be stealing from the American tax payer. I'm sure if NASA transferred the camera to a new owner, there would have been paperwork accompanying the item to include name and serial number. Other wise the person who "gave" the camera had no legal right to do so.
That being said, I do believe it was given to him but again, I don't think the person who approved it followed proper procedure for transferring ownership of the camera. So now its a "he said she said" situation.
