The “original” was a modified J18. The N7 was the “replica” of the “original.”The "Balabushka" in TCOM was made by Joss. I was under the impression that the Joss N7 cue was a replica, based the webpage's description of it as "the same style cue we made for the 1986 classic movie 'The Color of Money.'" But now I understand "same style" doesn't mean exact replica in the case of the N7.
