Mine met with a slight accident via my wife's foot. One of the ladders broke off (but I have it) and one of the finials on the same side broke and the broken piece appears to be gone forever. That's the bad news. The good news is she didn't mean to do it. I thought perhaps your replacement had a part number. Lionel does not have the Berks listed yet on their parts website. I'll be calling Charles Ro tomorrow.
I still have the one they sent me, let me know because I don't need this one.
