My doll looks very much like a Revlon Doll with a face most similar to a nurse, a bride(smaid) and a doll named Liz. The difference is that she has a bendable inner core and is covered completely with softer vinyl or rubber. Not jointed with removable parts. Is she a prototype or a different brand altogether? The only mark I can find is 157 on the back of her head (maybe 154)

I'm not sure but I have the same model and I have been trying to identify it for awhile now. I'll repost if I find anything.
