antique China doll replacement leg ID??

Hello
Does anyone have information about these kind of antique China doll replacement legs? To me they look and feel like wood but might instead be composition. Over the past 10 years two different antique China doll purchases had this type of painted replacement leg. The painting looks professional and I wondered if they could be something that the manufacturer offered which would date them as such. Finding 1 is one thing but finding 2 - what are the chances of that right? Thanking you in advance for any knowledge or insight you might be willing to share. Joan
