In the last entry we learned to deduce if we were looking at a model 15--or something else--based on the giveaway "runway" and "ski jump" of the machine's profile.
If it is a model 15, we'll next figure out if it's a 15-91 with the potted (direct-drive) motor, a 15-90 with the side-mounted (belt-drive) motor, or an earlier model 15 that might have been treadled, hand-cranked or converted to electric.
If it's a 15-91 or 15-90, it will have minimal decals on the arm, just saying SINGER with some slight flourishes (see top photo). Earlier model 15s will have more extreme, ornate decals on the arm and pillar, like these:

| Photo too small to see detail, but you can see a lot of gold on the arm, too much to be a modern 15. |
