Akpilot:

I would make a swag that these are ALL Estes manufactured and Centuri Relabled motors.


The oldest the Centuri B14 can be is 39 years old as 1969 was the 1st year Centuri sold the relabeled Estes B14.

Centuri stopped selling Estes relabled B14 in 1981. So this B14 is 27-39 years old.

Centuri also started selling Estes relabled C6 motors in 1969.

All of this information came from Doug Sam's fine Centuri-Estes Model Rocket Linage
Charts.

IF you have the time I would love to see a hi resolution phot of the B14 core next to a small ruler..... also could you measure on the inside as to how much distance their is betwen the end of the propellant grain and the end of the casing?
