I had a box of Centuri B14-6’s from 1976 and they did NOT have the deep, deep core like the older B14s had. The core was a little deeper than the average 18mm motor, but that deep, deep narrow core was not there.
I have some older Estes B14s (as well as some older Centuri labeled ones, which were probably also made by Estes) and they do have that very deep core and a very wide nozzle.
