KASAHARA SHOJI K.K.

The 1901 and 1930 charts agree with K193. FOTW uses the 1902 chart reproduced in Fune to Hata in 1994, but shows a wider top and an equal gap at the bottom.

The 1910 and 1926 charts show K206, except that the 1910 lower band has a wider gap. Alan Watt suspected an early version had changed before 1910. The device appears to stylise the lower half of the first kanji of Kasa.
