I don't think it was specially for woman and children, and it's perfect too, because it was very more expensive than alto and children, and sorry, but at this period who work, wo have money, who is dominante in family at 1928-1930. It was essentially a man.
It was complicated for woman to pay one, it was more expensive, it's okay for richess woman, and richess children
I think it's better to create one another product to replace c melody or soprano and oriented this New product for a new market : the orchestral. With this product, i think it's more for attracting the classical player in orchestral with this instrument, that for woman and children. At this period the selling of soprano and c melody fall and it's probably to replace this two product without great sell, it decided to create this horn with different orientation : the classical player with the classical orchestral band.
If in originally, it was for children, or woman, my asking is why create conn-o-sax which absolutely not adapted for Child and "woman" too.
Maybe it's more a projection to opportuniny to create a new market with classical player and orchestral band.
And other question, why it choose F tonality if it's perfect adaptated for woman and children, why don't take an alto in Eb and simplificated system to win in tall, without all keys, just with low D at high C, couesnon made at this period an alto with simplificated system, and it's "baby horn" because is shorter than alto in Eb but without plenty keys : in low, 'it stopped at low D flat and it grow up max High D flat.
With less key, you're shorter alto in Eb.
Why you don' t choose a simplificated system, humm for me, conn mezzo soprano is more adapted for classical player and to replace english cor and French cor (basson) which has it period and today too, it was long to product, it was expensive to buy one, and you have long time waiting to received one.
With conn mezzo soprano, it was modern, it was adapted for classical and it could be product in mass easily if the production is success, and it cheapest than French cor, than english cor, or basson.
Maybe to have another choice at oboe too.
Or create a new market for classical player, that at this period the saxophone wasn't greatly accepted by classical orchestre.
It's just my theory based on logical fact
