sorry we ended up hijacking your thread so much
My intent as the OP was to start a discussion about how to determine what is a valid Z-Grill. I asked for more high quality photos of Z-grills (and E-grills) with the intent to allow others to better determine what is a Z-grill and if the grilled stamp they have is in fact a Z-grill.
As to the stamp which "took us off topic" (it did not) it was I who added the illustrations of the stamp the first time it was mentioned as a questionable Z-grill. Discussion ensued, the stamp was soaked to better reveal the grilling in question, a normal and common practice which in this case was in fact necessary to fully reveal the grill in question and for the conversation to continue on topic. Also on point for a newbie to learn how to do good grill identification when the is foreign material on the back of a
used stamp.
As Don said thread are monitored for "on topicness

" and I am fully able to send a message if I feel "my" topic is now running around in left field when it started as an iceboat race. However when that occurs, that is what makes this Smilie

so wonderfully needed.
I even purposely tried to start a discussion by showing the first two grilled stamps, claiming what they were and stepped back to let the comments begin before I added the two certificates.
In summary this thread was created to help ID Z-grills (and to a lesser extent, non-Z-grills). So far it has exceeded my hoped for content. Now of course if a cert is gotten for the blue checkered canceled stamp, I expect it to be posted here to complete that portion of our discussion.
As to Don's comments, I have started I think two threads which, after one off topic political comment was posted, jumped off topic quicker than a Space Shuttle solid rock launch. The useful content just disappeared into the fog of politics and vanished into wherever a moderator needs to send the offending electrons.
So far,

to all contributors to this thread.
