The Cox Dyna-Soar and the Cox Astra Glider were two different models, even though they both were given the same catalog #5085. See images below and attached cover letter/order form provided by Earl in the following thread for reference: https://forums.rocketshoppe.com/showthread.php?t=19414

The April 1970 issue of Model Rocketry Magazine: http://www.ninfinger.org/rockets/Mo...02n07_04-70.pdf , page 11 (frame 13), shows the Cox Dyna-Soar prototype model and the Saturn V that were to be introduced in late Spring 1970, but, to my knowledge, the Dyna-Soar did not ever get released. I don't believe that the Cox Saturn V launch tower was ever released either.

Later, in the released Cox Launch Control Instruction Manual, the last page (shown below) provides some additional clues on the dated release of some of the Cox model rockets. Both the Uprated Saturn 1B and the Saturn V models show availability as of June 1970. The #5085 Dyna-Soar shows an availability as of June 1970, but it never materialized.

The Cox Astra Glider was a swing wing design as seen in the Vintage Cox Model Rocketry Poster tri-fold brochure, but it also did not ever get released.

According to Earl's post https://forums.rocketshoppe.com/sho...84&postcount=16 from the https://forums.rocketshoppe.com/showthread.php?t=19414 thread, the poster and cover letter/order form were in an envelope postmarked May 1970.
