Many of these displays have been out of stock for years, and all are the last of the last in terms of current availability. When we offer a series of numbered limited editions, we are careful not to oversell the material, since its typically impossible to obtain more of it. Occasionally, there is a bit left over after the displays are gone from the Cole's Aircraft store, and sometimes there is enough to offer one or two additional displays. Regardless of the quantities listed in these item descriptions, each of these displays will be signed and numbered 'Special 1/2' so as to beat maintain the integrity of each series - but it would be a travesty to allow these last remaining pieces to remain in storage. We're offering them, here.
