Your dolls head was made by Armand Marseille, I think for George Borgfeldt, the 329 denotes a character head.Not sure of year, but since bent baby bodies appear to be made after about 1909, she was probably produced between that and the 1920s... Her head is bisque and her body is a 5 piece composition baby body type. She looks gorgeous!
I'm not an expert, but I've been collecting for a lot of years and have a wide range of antique and collectible dolls. I love researching, I love to pass on knowledge, I never mind being corrected....This is a hobby where we never stop learning......
