At an estate sale southwest of Fort Worth, I recently acquired a Lenco Sewing Machine.
There were many sewing machines produced by Japan post WWII. They had machinists and manufacturing facilities, and they needed to turn their resources to non-military activities. They acquired either an actual Singer sewing machine or plan details for manufacturing them, and they produced many machines that were inexpensive and were shipped to the U.S. for sale. These machines were made very well and were very sturdy. Sold under many name brands, and even branded for department stores to sell as their own, these were very popular machines. They were so well made and so sturdy that we still have many of them available today.
This Lenco was in good working order, and I have cleaned and oiled it. This machine is available in my Etsy shop http://www.etsy.com/shop/irishroseneedlearts.
