Hello, This is a pretty little American Girl I picked up this week. I believe it is a "Z". This one looks very 50's to me. I can just imagine a gal in the dresses they wore back then wearing this one.
The case is 10k gold filled and date stamped L2. It is yellow gold filled with engraving in white gold. The bracelet/bangle is also yellow gold filled and it came with a safety chain.
The movement is date stamped L2. It is a working 5AD 17 jewel movement. The crown has been replaced.
