Dollhouse is new in box from 1950s. Model 100 and you can see by instruction paper which Model is in box.
The instructions are for model 100 and 101. I tried to make sure of parts but it has no parts list, so by picture only I think it might be missing the shower curtain rod, close hanger rod for closet and shower vanity and closet doors. And those are cardboard like cutouts besides the rods.
