I've seen the single platform U-156 photos, Stan, so that's why I was curious. It appears that the illustrations provided here may be what the typical configuration was, but not necessarily the variations. It also appears that virtually everyone refers to it (the U-156) as a IXC. I may have to mesh both a IXB and IXC together to get what I'm after, as the IXB certainly seems to look more the part.

Thanks a bunch,
Kevin
