This just helps with IDing what kind of doll one has......
http://antiquechild.com/category/china-doll-types-era-details/"Lowbrow China dolls were the end of china doll production and made for 40 years. Those that could not
afford the ”new” bisque head dolls with ball jointed and leather bodies and REAL hair had to settle for
a “cheap” doll. China heads were sold in parts of heads, arms and legs through catalogs like Montgomery
Ward, Sears and Roebuck and Wards. If the buyer could not afford arms and legs, a head was purchased
and the other parts were made from materials at hand. When a part broke, another could be purchased. "
