VINTAGE CLOTH DOLL WITH MASK FACE

This item was sold at a goodwill along with another cloth doll as a combo pack in a plastic bag. One look and I knew something was different about. I paid $7.00 total for the both of them. It appears to be VERY old. Handmade but unsure of the date period. The clothing is very dirty and has some stitching coming out of the green dress. The face appears to be of a plastic (mask). The back of the head is cloth. The legs are attached with some kind of metal clamp along with a plactic disc?? The body is filled with a sawdust material. Due to the metal attachment on the leg and possible age of the doll some of the filling comes out of the loose areas around the metal attachment. I have not been able to find this doll type anywhere. I've tried sereral auction and collector sites with no luck. From the looks of it.. it must be very very old and possibly stored in an attic,garage or unfinished basement(room) based on the dirtyness of it. Unsure if I should wash the cloth's or even sew up the stiching that is coming out. Would that change the value IF worth anything?
