I have a brown one, but have only seen a few, they come in black as well. Most are missing the front cover... I have never seen one working! Perhaps they are somewhat overlooked by collectors, as they look much like ordinary 17"-19" portables of the era?
In the thread "A Little Flat Tube Fun" one can be seen on the shelf next to a Philco "Safari", that I am comparing to a flat-tube Sony "watchman":

We have had several discussions about the first commercial transistor sets...I think
most agree that the Safari was the first, but the 8" Sony and the "Astronaut" are close contenders for #2 and #3 ranks.
