Dear Nick,
I stored Bruce's Mook Jong in my cellar for several years. When I moved from CA to Colorado recently I found the dummy very much in disrepair:only the "arms" and legs" were intact. The body was ruined. I gave the pieces to Mark Mikita, my long time MA instructor. He mounted the few intact pieces on a board. They are now on the wall of his studio in Venice, CA..
best, Joe Hyams
Bruce brought his Mook Jong (Wooden Dummy) over to Joe's house when they trained privately in the late 60s along with Stirling Silliphant. When Bruce moved to HK to make his movies he gave/lent Joe the Mook Jong and told him to go and train in Wing Chun.
