1930s brass and cast iron spiral stair

My wife and recently purchased a townhouse in Park Slope and are in the midst of renovating. As we have two boys under 2,we’ve decided to remove a spiral staircase that connects the parlor floor with the first bedroom floor… Can anyone recommend a resource for me to contact to try to sell it? (and/or value it)? It is brass and cast iron and I believe it was installed in the 1930′s… Any help would be appreciated.
