At this point, I'm going to assume that Speedman3 is out due to no response in spite of several attempts to make contact and invoice reminders, so slot #6 is open to whoever wants it.
Also, a progress update...the plant is currently in the process of converting the prototype part numbers over to sell-able part numbers. As soon as that is complete, they will provide a more definitive production schedule. Once that schedule has been confirmed and verified by me, I will make a new thread dedicated to mass production and delivery updates.
