KC, the ceramic liner is still intact and not broken. That's a good site, I also have the Captains Teapot and Serving Tray that are similar to the ones listed on that site. In the pictures below is a Silver Plated 5 1/2" Teapot I purchased fairly recently. The NYC Lines is the New York Central Railroad Lines I think, not sure how old the Teapot is.
Thanks,
Kevin
