Morimura Bros. Mark used since 1911. My favorites of my collection

All three are over 100 years old. How I've determined this? The McKinley tariff act of 1890 stated imports had to have the country of origin. Nippon is another name for Japan but in 1921 they had to change it to English and this is why we have Made in China, Taiwan, exc......

If you believe otherwise please, by all means correct me on this because corrected knowledge is still knowledge.
