Sorry about that as it is my assumption since modifications were obvious from the initial unit that obviously had been previously demonstrated.. I made the assumption they were requisite changes but truly have no idea if that is the case.
I would bet they wanted a demo because there is something else added to it since it was first demoed. Some new features possibly? Just a guess. Btw, have you seen the shareholder list from the transfer agent and that's how you know where you stand on the list of owners?
