Antique, Double Doll, Red Leather, Wood, and Metal Baby Carriage

I inherited this from my Aunt Lib. She was considered an "old maid"; she lived alone with her cat. She is of English descent. I have no idea if she owned the carriage as a child or, if not, how she may have acquired it. Judging from the groan which arose among family members at the reading of her will, it is believed to be of considerable worth. I wasn't expecting to receive it; apparently she left it to us because we have a daughter. It does not appear to be marked. I could not find anything directly comparable to it on the internet. I did find one site which stated that no antique doll prams we ever made of leather so, if it was correct, either the interior is faux leather or it was custom built. The only significant wear is on the hood. It still functions but, while the silk is completely intact, the leather is worn in half. There is also a screw loose upon one of the bars (attaching the push handle to the wood frame). Those are the only condition issues I detected. My aunt was a compulsive duster; however, beyond that, it does not appear to have been cleaned in recent years. That's about all I can tell you. Please refer to the pictures for visual illustrations.
