Grand Master Harold Long I believe was a student of my old sensei Seiyu Oyata. Renshi Ryukyu Kempo here
He was a student of Tatsuo Shimabuku in Okinawa...This was in the early fifties when he was stationed in Okinawa after serving in Korea...He was a Marine at Chosen Reservoir...
He very well could’ve been...I only know of Grand Master Shimabuku who I met once in Knoxville, Tn...
Watched him burst a floating balloon with his “shuto” jab...
Hail Vitus!
