adbinc@fbc7e25 That is one of the clear stands that originally came with the Starline 2500 miniatures. Amarillo Design Bureau sells them on its shopping cart ( http://www.starfleetstore.com/) as product M-2500
I hope that helps!
adbinc@fbc7e25 I chatted with the designer and this is his response: It is dimensionally identical to the legacy ADB stands, but not to the Mongoose stands that ship with Starline 2500 (1/3125 scale) ships.
The pegs at the top of both types of stands are nearly identical (within hundredths of an inch), but the heights of the "riser" stems are quite different.
