Singer seal dating process consolidating memories
The 221 was introduced at the 1933 Chicago World's Fair, and a commemorative medallion exists on machines marketed at that event.
There is a 1936 seal for the Texas Centennial Exposition, and a 1939 seal for the Golden Gate International Exposition in San Francisco.
Machines in good condition can still be found at bargain prices in garage sales and auction houses.
Advertisements in quilters' magazines bring higher prices.
Quilters, therefore, value a machine that can sew a straight lock stitch without the slight zig-zag that characterizes the straight stitch on most modern machines.
The featherweight, although constructed of aluminum and thus very lightweight, runs smoothly and quietly due to its well-balanced rotary-hook mechanism.
The highest-priced machines are in good condition with little wear on the gold leaf, complete with case, attachments, and original manual.
The predominant finish on the 221 is a shiny black.
The most- interesting designs were seals from machines marketed during various expositions.
In addition to the cases, Featherweights were sometimes sold with specially-designed folding convertible card tables, with a removable section for the machine.
These tables are somewhat rarer than the machines, possibly because of their convertible design.
Older cases have an accessory tray that stacks on top of the machine, which is set down in the case.
The newer cases have a built-in side shelf for accessories and bobbins, and a place for the foot pedal on the inside of the case cover.
