Vintage Cox Model Rocketry Poster tri-fold brochure
 
3 Attachment(s)
Some may find this a bit of interesting L.M. Cox model rocket history. It is an early Cox Model Rocketry Poster tri-fold brochure. It includes a swing-wing glider illustration and description called the Astra Glider, which was never released but would have been unique if it had, because all of the original Cox model rockets were constructed of injection molded ABS plastic and were ready-to-fly or almost ready-to-fly. This poster/brochure was pre-1972, because Cox issued it's initial Model Rocket Catalog in 1972: http://www.ninfinger.org/rockets/ca...2/72coxcat.html , which was more developed/formalized than this earlier poster/brochure which only featured artist renderings of the Cox model rockets.

Sorry, I wasn't able to do a continuous scan to keep the tri-fold poster all together. Perhaps someone with some graphic skills can stitch the three pages back together. This tri-fold poster was the interior of a Cox Model Rocketry Poster/brochure. I'll also submit the exterior pages in another post on here following this one.

I'm hoping that someone who knows, like Bob Sanford (Initiator001) or someone else, can fill us in on more of the L.M. Cox Model Rocket history.

I recall that the igniters, and pad, were different. Pre-production concept drawings!

Liked their 18mm D8-3 and D8-0 motors.
Don't think a 13n-sec motor is possible in a 70mm case now with the weaker BP Estes now uses.

They apparently didn’t keep the “Astra” moniker going forward either. I think the Cox stuff first entered the market about 70-71.

All of the Cox D8 motors I have are dated sometime in 1971.

Have you flown any of your D8s? Curious about performance, not sure I’ve ever heard about performance, or even reliability.

I flew a Cox D8-0 at NARAM-52.

There are some clues to help date the introduction of the L.M. Cox model rocket engines and kits as well as the Cox Model Rocketry Poster/brochure. Notice in the Cox Astra Engine illustration on the brochure, there is a 1969 date on the engine label.

Also, later, in the released Cox Launch Control Instruction Manual, the last page 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. Plus, the igniter illustration on the last page of the Cox Launch Control Instruction Manual shows a different style of igniter than the Astra igniter. The style shown in the Cox Launch Control Instruction Manual is the style that Cox ultimately released instead of the Astra igniter with sockets for the two prong connector shown in the Astra Launcher illustration. In addition, notice that Cox added legs to the Launch Control Pad that was actually released vs. the Astra Launch Control Pad did not show any legs on it.

These clues lead me to believe that the Cox Model Rocketry Poster/brochure was likely printed in late 1969 or early 1970.

Don't you wish we could still get motors at these prices shown in the attached Cox Engine Order Form? Notice the Cox engine specs and the igniter details for the released versions vs. the Astra version shown in the Cox Model Rocketry Poster/brochure.
