Default Blue paper Centuri B14-7 motors?

Anyways, on Christmas day, my sister in-law gave me 4 packs of Estes motors that had belonged to her late husband. They were in the blue diamond tubes and there was one tube of A8-3's, two tubes of B6-4's and one tube of C6-3's.

When I took them out of the tubes, I was surprised to find that they were the green colored motors. The nozzles on these are smaller than current motors of the same type.

When I asked how they were stored, I was told they had been in an unheated attic up here in the northeast for probably the last 30+ years. I assume that they are CATO's waiting to happen.

I was thinking that I could build a few Midnight Express paper rockets to see what happens since they have had severe temperature cycling but them decided to see if anyone wanted them.

I am not a motor collector so they don't have any more value to me than a current motor, but I understand that there are a few collectors out there. I am planning to attend NARCON in Connecticut this year so I can bring them with me if there is any interest.

Pictures:
1. Blue diamond tubes.
2. One each of green A8-3, B6-4, C63.
3. Nozzle comparison with current motors. L - R: A8-3, B6-4, C6-3
4. Nozzles with a scale in the picture just because Terry Dean is going to ask for one. L - R: A8-3, B6-4, C6-3


*I think I'm going to colic in my stall* In 1972 or 1973, my father and I burned through dozens of these green motors. We thought they were 'just' the latest innovation from Estes. Had we known "the rest of the story," we would have salted some away as collectors' items!

I do, however, have one Centuri B14-7 motor that is made of blue paper with black lettering on it. The nozzle is dark gray like pumice soap (it looks like the nozzle material in the German-made MRC 18 mm motors of the early 1990s). I'm fairly familiar with Centuri's motors, and I've never seen one of these before.
