Douglas - thanks for reaching out.  I took opportunity to read through (thoroughly enjoyed, educational beyond description).  I will be looking to sell if you are interested.  Thanks again for following up.

Sorry Antonio at this moment I do not have any issues for sale. I am currently in the collecting stage.
