I did research on Starline baseball gloves and found info on the H.K. Buttons.... The "H K" entity owned or directly contracted the physical tanneries and sewing factories in Japan. They cut the leather, stitched the gloves together, stamped the "Starline" and player names into the palms, and pressed their proprietary "TRADE H K MARK" metal buttons into the wrist straps. the company acted as a "ghostwriter." Small, independent American wholesale import firms (trading companies based in New York, San Francisco, or Chicago) would travel to Japan, buy thousands of these completed "H K" gloves in bulk, and handle the actual shipping and customs clearance into the United States.
Because H.K. specialized in mass-volume, low-cost exports, they engineered generic, highly adaptable glove patterns. To maximize profit, they used the exact same physical structural frame for multiple players. For instance, the FG-8 (Mickey Mantle) and the FG-9 (Ralph Kiner) and FG-11 (Bob Feller) were fundamentally identical glove builds manufactured side-by-side in the same Osaka workshops; the assembly line workers simply swapped out the palm stamp die depending on which baseball superstar's name they were printing that day.
The "H.K." insignia on your glove's wrist button represents H.K. Trading Co., Ltd. (H.K. Boeki Shosha), operating primarily out of Osaka, Japan. Following World War II, the General Headquarters (GHQ) of the Allied Powers structured Japanese industry to prioritize export-led recovery. Smaller manufacturing tanneries were grouped under regional trading umbrellas. Osaka and the nearby Hyogo prefecture (specifically the towns of Himeji and Amagasaki) were the historical epicenters of Japanese leather-making and sporting goods production.
The explicit inclusion of the words "Trade" and "Mark" surrounding the "H.K." initials inside a baseball stitch pattern is a crucial historical clue. Under Japanese export control laws of the 1950s, the Ministry of International Trade and Industry (MITI) required designated export trading houses to register unified, stamped hardware trademarks. This ensured quality control accountability for outbound shipments before they reached American ports. You will find this identical "TRADE H K MARK" button on other vintage Japanese-imported lines from that era, including Marlin Brand youth gloves, Cragstan Models, AFI (AFI Accessories), PAL, Good Luck Japan, and Cambridge baseball gloves.... If anyone has other brands with the "H.K." button please let me know so I can document it on my website. Thank you -Steven KeyMan
