It looks like the "real" teapot - very smooth, fine casting, small porcelain knob - but only the top piece has the lettering, there is none on the bottom. It is definitely magnetic, so must be cast iron; you may be right about the nickel plating, that could account for the dull patchy silver-gray color on top and brighter silver on the bottom. I don't know much about Wagner, but have seen plenty of repro cast iron pieces of other items, and they all seem crappy compared to the originals. I think this is truly old - so did the manager of the multi-dealer flea market where I bought it for $50 - tried to buy it from me!! Unfortunately I don't have a digital camera, just a scanner, as I collect/buy/sell postcards, and that is all I need. If you really want a picture, I can have a friend take one for me. Thanks for your help!
