I think you've got the wrong Korean spouting 2000 yr-old propaganda if you refer to Grandmaster Kim Pyung-soo:

But, you can find re-prints from his 1966-68 articles in Black Belt Magazine from time-to-time. Some of those mention the 2000 year-old-type connection. But understand, when he wrote those he was still living in Korea and under the tremendous scrutiny of other martial art peers and organizations. Korea was not really free like you have in America. He heard cries of "you're not a Korean, you're a traitor" for publishing information about some of the kwans at other times that linked their lineage to Japan. This is the primary reason he immigrated to the US in 1968 - to have the freedom to express his knowledge without fear of censure.
The Palgue 1-2-3 book was written in 1973 when he was already in America. Probably he wrote about the statue in a "Taekwondo stance" because the stance is used in TKD (also in many other arts) and the book was a "TKD form book." He dedicated the book to Kim Um-yong, to help show the English-speaking world the new forms (Palgue) from the KTA. He certainly didn't believe in the 2000 yr-old story - he lived through the Japanese occupation and witnessed the martial art school development during those years and following the Korean War. If any of you have read a detailed history book on the kwan development in Korea, you know how much paper that can take up. I think he just tried to save time by publishing a history version he wrote for Black Belt Magazine and focus on the forms. I'll ask him when I see him in a few weeks when I visit with him why he did that.
Terry,
Already the kwans weren't even allowed to use their kwan name anymore by 1967. They (the kwans) were all assigned roll call numbers during KTA events and weren't supposed to use a kwan name - due to the attempt to unify under the KTA TKD banner. They created the new forms to have a unified list of forms in which to grade students from the various schools. This is the whole reason for the new black belt form creations (1967) and the the gup-grade Palgue forms in the 1970's.
The Black Belt forms in 1967 were a collective effort of some heads of various organization, not just one kwan - though I am sure one may have had instructors with more influence.
FYI: Before their creation, Grandmaster Kim Pyung-soo (as with any kwan not associated with Choi Hong-hi) knew zero TKD forms (they weren't created yet). He knew karate, chuan-fa and bong-sul forms.
Please let me know if you have any questions you would like to pass along to Grandmaster Kim Pyung-soo. Any of you could contact him directly as well.
