Sorry just seen this. Well I certainly think she looks like a hasbro Sindy but the markings aren't consistent with that I don't think. Have you managed to identify her?
So many dolls that I never heard of. Big Jim, Sindy, Maxi. Such a sheltered life.
Haven't identified her yet, trying to see if UNIMAX was outsourced by whoever had the rights to produce Sindy or any other company. I haven't been able to find any barbie style dolls produced by UNIMAX everything I saw looks nothing like this doll.
It is a Defa Lucy, and from the website I finally found looks like a mix of Sindy and Barbie clones. http://unimaxtoys.weebly.com/fashion-dolls.html all though I wouldn't mind get a hold of some of those furniture sets.
