Regarding National Tournament Cue: There are numerous sources here on AZB and other sites, including the Blue Book, that erroneously attribute a "National" logo to US made cues.
I will clarify that here. The logo pictured is on cues made in Taiwan by Kao Kao.
The "N" logo cues were also made in Taiwan by Kao Kao.
I have never seen a made in the USA National cue with any markings printed on it. This is an original National Tournament Cue sticker on a made in USA cue.
