At a guess, the day hell freezes over.
I think a better answer (since not everyone is familiar with the history of this prop, nor the similarities between it and other planned offerings from QmX and others) is that it's really hard to tell.
History has shown us in the hobby that replica prop companies are not always dependable in their release plans. Some companies are better at it than others, whereas some companies that were once consistent end up being disappointing.
Over the years, I have seen MANY offerings with specific delivery dates that failed to come to fruition. Sometimes the dates get bumped once or twice, and then delivery finally happens. Sometimes the dates get bumped a few times, and then the product line is announced as cancelled. Sometimes there is no announcement at all, and the product just slips into oblivion.
Even worse, sometimes the company doing the offering simply goes out of business, or trades hands, or switches gears.
From what *I* have witnessed, QmX is very dependable in delivering paper props, and other tchotchkes, which tend to not be of much interest to the collectors of this forum. They fail miserably when it comes to delivering replica props.
I have assumed a VERY skeptical stance toward any company that offers prop replicas, UNTIL the day they start shipping. I'd much rather see a production run with a few quality issues and accuracy concerns than a "perfect" replica that never materializes.
