I was researching something else, and I came across this topic. Now, Perhaps others know this, but I did not, and am giving people a heads up. No wonder my 1980s sewing machine from singer works better...
I got the paragraph from http://www.geocities.com/claw.geo/singer.html
During the Second World War, Singer (as the other American sewing machine companies) ceased sewing machine production in favor of manufacturing equipment deemed more necessary to the war effort. As a result, this led to a great shortage of sewing machines immediately after the war. By the mid-1950s, however, the market had become flooded with foreign made machines. European models possessed more features than the typical American models. However, the greatest threat came from Japan which dumped millions of cheap clone models on the market, driving all of the other American sewing machine companies out of business. The American manufacturers could not compete with cheap Asian labor and Japanese industries (paid for largely by the American taxpayer as a result of the Marshall Plan).
While smaller American manufacturers including New Home and White struggled and eventually succumbed to the onslaught of the Japanese companies, Singer was able to survive. However, Singer fared little better, with its market share having shrunk from 75% to a mere 25%.
Although the Singer Company still exists, they no longer manufacture sewing machines. After closing their last American factory in the 1980s, the company eventually sold off its sewing machine related assets. Singer is currently an aerospace company which does business mainly with the Department of Defense. The Singer sewing machine brand name is currently owned by the German Pfaff sewing machine company. Today, machines labeled SINGER are generally “badged” models manufactured in Asia by foreign companies.
A number of replica sewing machines have been or are currently being manufactured in Asia and labeled as SINGER machines. These include the Models 15, 20, and 221. They are currently being sold in North America as “vintage reproduction” machines. Collectors should be aware that these machines are of generally inferior quality to antique examples. Moreover, their relatively high prices do not make them a good buy.
