I'm in the process of cleaning out my machine storage closet, and realized that I never shared my 1956-58 Singer model 15-125. Let me introduce you to this green wonder!
This model is a basic upgrade to the very popular model 15-91, and was the last of the direct-drive potted motor straight stitch only machines.
The changes to this model 15 were all cosmetic, including a more streamlined head and two-toned green colors. Even the cords and foot control were updated to match the new color scheme.
Even the light casing and cord are green, which looks pretty good with all that gold branding.
