The Eureka line of Japanese kits was sold in the U.S. by Eureka Importing Co. of Oklahoma City. The company was owned by Jerry Asner; Jerry was a GI in Korea and spent time in Japan in the early 1950s. An active modeler, Jerry made contact with a Japanese model company through his model flying activities in Japan - he took samples of the kits back to San Diego when his tour of duty was up. Getting some positive response to the kits, he went back to Japan and obtained permission to export kits to the U.S. for his newly formed international company, Eureka. The all kiri wood kit was unacceptable to the U.S. market so Jerry manufactured balsa parts in the U.S. to replace sheeting and large blocks; the precut kiri wood bulkheads, ribs etc. were retained. Balsa wasn't available in Japan at the time.

The advertisement shown below is from the February 1956 issue of Flying Models for the San Diego Model Shop. I suspect that this was Jerry's initial effort to sell the Japanese kits.
