Antique Doll with China? Head and Limbs Soft Body H.A. 2-78

Hello :) !!

I am a collector of what I and others would consider "ugly dolls" however, sometimes I see one that I just think is pretty. Such as this one I picked up earlier today at my local thrift shop.

Anyway, I don't know how to go about finding anything out about dolls so, I decided to look around and found this website. I am hoping someone can tell me more about her as I haven't a clue. I'm not even entirely sure of her composite..

Here are some details about her. 

• She measures out to 21 1/2 inches tall
• She is marked H.A. 2-78 at the base of her structure
• She has some light staining in spots
• She appears to be entirely 100% in tact, no chips
• Light paint wear at pupils in eyes and at top of a boot
• Please see all photos for Full Description

I would consider selling her if I just knew anything about her.

Thank you in advance,

K.H.
