I am going to post pictures of some of the older motors in my collection. I started in 1967 and have been a NAR member from 1968. Served on S&T and other NAR committees, but my military moves meant that I usually could not chair a committee long. Was on the Board of Trustees for nine years.
My motors are stored in a way that only the ones used for flying are readily accessible. When pulled out they all looked like this. The red ammo can was the first.

I do not claim that I have all of the motor histories or are totally accurate in my recollection. I welcome any clarifications or additional information.

Model Missiles Inc was set up by G Harry Stine. Brown Fireworks made there first motors based on Orville Carlilse's half-inch motors, but in the now standard 0690 x 2.75 inch size. One live motor and one flown in a Camroc at NARAM 15.

Estes B.8-6 from '68, B .8-5 from'67, and a C.8-0 booster from '67. NAR newsletter said that the C was certified in 1963. Old pound- second designation.

Second photo is two Estes B16 motors at the bottom - the nozzle is on a B16-5. No date codes. Designation was based on an incorrect reading of the test equipment they had at the time. Above them are a Centuri B3-5 and the nozzle of an Estes B3-5 from 1967.

According to Stine the Uni-Jet motors were produced in 1964-65. They were 0.5 x 2.25 inches. They had a propellant that did not age well and they became unreliable. They were equivalent of 1/2A motors. The ones I have are a D2, D3, and D4. I believe the number is the delay. The nozzle is one the D4.

The pride of my collection is a Prodyne. NAR newsletter said that they were certified in 1963. This is a Prodye Hurricane BE-3.5-2-8. NAR equivalent D2-8. Their larger motors were Cyclones in E and F impulses. Again, the old pound-second designations
Second photo is the nozzle.

Final for tonight is for flying your Estes Omega with Cineroc. D12-0/D12-7. Date peeled off of booster and the dash 7 was made in 1971. More later

Very Nice Pics.
Especially the B16-5/B3-0
I know at one point Carl at Semroc was going to re-create many of the old core burners, but he never was able to get back into producing motors before he unfortunately passed.
He truly was a one-of-a-kind gem to our hobby we likely will never see again.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !

Thank you for remembering Carl. During the last few months, he and Bruce were working on the BP engines. They had the building finished and they were testing some they had made. Needed some tweaking but we were close. BTY, Bruce did not include the engine machine with the sale.

Hello, Sheryl.

We, in the rocket community, will ALWAYS remember Carl as a true innovator and gentleman. Those who met, and talked with Carl, you and Bruce, have nothing but great memories that will live within us. Thank You, for all you have done, for all of us.
