I am shutting down this post. Some posts have been edited or deleted, so that the useful portions of this thread are available to future viewers. If this bothers you, either go elsewhere or complain to the owners of The Forums.
I do not think that either poster with parts intended to use this forum/thread to sell parts. Other members have other opinions on motivations - these opinions are not pertinent to this thread.
Posting information about parts (part numbers and photos) is beneficial to all of us (now and in the future).
Brad, thank you for showing us an interesting, odd, and uncommon part.
