Hi, Mike. The photo was taken in March, 1958 when I lived in Buffalo.
From left to right, Jr Ringmaster/OK Cub 19, Scientific something or other, VECO Tom-Tom/Fox 35 CS, flying wing made from a Wee Duper Zilch/McCoy 098, Circus King/Fox 35 CS.
In my hand, a profile Hell Razor/Cox Space Bug 049.
The Circus king was a great flyer. As far as I know, it's identical to the Ringmaster except for the shape of the tail/rudder. Should be OTS legal.
