If a transitional lacks a pontil and is still from Japan, Nakanishi could be a possible maker. He came from a samurai family in Osaka and also ran a large appliance and gas company—the biggest in the city at the time. In the marble field, he filed utility model patents in 1932 and 1933. The 1933 utility model 18246 describes a marble-making machine equipped with a burner to fire-polish a cut end of transitionals. He also made cut glassware.

An advertisement for Nakanishi marbles appears in Industrial Nippon To-day, published in 1935. The production volume shown in that ad is larger than that of Isogami when he switched to machine-made marbles in 1939. Isogami had fully automated production with 14 workers, turning out 1.5 million marbles per month. The number in the ad suggests that Nakanishi may also have transitioned to machine-made production in 1935.

Thank you for that, very interesting. From appearance would you think this is actually Japanese?
