I have an old John Heiffor straight razor that belonged to my dad. The thing that confuses me about it is that it has an etching on on the blade of Constantinople done in great detail with the wording underneath World's Fair at Constantinople 1895. All my research says there was no fair in that year at Constantinople. I have also tried referencing it with the 1893 expo but nothing matches. I have been trying to get the history of this razor for some time but seem to come up short. Its a great razor and since its a family thing I certainly plan to keep it, but would just want to know a little more about it or to be able to properly date it. It's also nice and sharp and I have actually shaved with it. Anyone thats run across this item or has knowledge of it please give me a yell. Thanks. Charlie
