I just bought one today for $20. I’m a novice with dollhouses and don’t know anything about dollhouses but I am an artist and hobbyist who is up for the challenge of restoring and modernizing it. But it’s missing a few windows, stable doors and electrical. Want to restore it for my granddaughters but don’t know where to find the missing items without paying a lot for them. The railing on the stable level is also missing. I bought some doors from eBay and a transformer from amazon which I hope will work because I have no idea how the lighting works. Any ideas of other dollhouse railing can work?? What is the scale? Couldn’t upload a pic from my phone but looks just like yours but with missing doors and windows. What is the big hole that looks like a window in the back for?
