Browsing through
ebay, I'm noticing some unlikely precancels. The precancel itself appears to be valid on these stamps, but not used on the issue it appears. For example, there is this one:

I'm no novice when it comes to precancels, and I fully understand the concept of favor precancels. I was under the impression, though, that precancels - as valid items in the postal system - have gone the way of airmail stamps, postage dues and the dodo bird.
Am I mistaken?
