It looks right to me, and it's spot on for a 201. These models take general low shank feet, most of the accessories for these models have identical part number, except for a few of them; feed dog covers, darning foot for the 99, I can't think of any more at the moment; maybe those odd things used when sewing ribbons and cords to the fabric can be model specific. Bobbins are correct. The 3/4 size machines like the 99 and 128 generally take the same low shank feet as
the full size models.
The 201 was introduced in 1928, by then a lot of the feet had become hinged; the earlier tend to be rigid and one piece metal, but generally they will work fine with any low shank model. My 1934 99K has the solid one piece standard presser foot so there were quite a few years before the hinged variety were all over standard. The 201 came with a small metal handle screw driver, some other models came with a black bakelite handle, but otherwise identical. The larger screw driver is more bent one piece metal thing and usually the same for all models. Ruffler and pin tucker should be the same for these models (at least the one with the ruler that adjust width with a setting screw).
This is a guide to identify a low shank foot from the rest. With the 201 you don't need a feed dog cover anyway (feed dogs are lowered), the darning foot is often missing. I think the ruffler was bought separately, but they are often with these old machines.
