W & w
I have my gramma’s Wheeler & Wilson. My serial number is 244118. There are several patent dates on the throat plate, first one is August 2, 1878 and the last one is March 25, 1890. My machine was made in the 1890’s (after the last date) in Bridgeport CT where the W & W factory was. I think Singer bought them out around 1905 but continued selling W & W until 1908.
