These are all styles of the sew / darn indicators for the 222K Featherweights. The chrome indicator was the standard issue on 222K Featherweights from 1953-1954. The most common black sew / darn indicator with the silver outline came on all Featherweight 222 machines from 1955 through 1961. These original indicators will also come with original screws, (chrome screws for the chrome indicator and black screws for the black indicators.) If you have any questions feel free to
