I've taken it upon myself to do just that -- I went and bought a (basic) set of calipers and spent a couple of hours with EAGLE putting together a library for the NL-5440A plus SK-185 socket. This utilizes 21.5 degree pin spacing and resulting 37.5 degree gap, which fits my observations of the socket itself quite well. I even printed a copy of the footprint on the office printer to check things out -- looks basically sane. Thanks all for the help!
Here's a link to my dropbox, in case you have a need for such a thing: http://dl.dropbox.com/u/709108/EAGLE/NL-5440.lbr Share and enjoy. This socket actually fits quite a few nixies, but I only have NL-5440As on hand and didn't bother adapting symbols for variations on the scheme.
