I have a 1950s 6/8 half hollow grind T-I though not so marked, I got in Paris at a cutlery shop years ago.The guy who sold it to me said it was from a batch of steel cast by Jacob Holtzer of Chatellerault, a very famous steel worker, d 1900. I notice in a current T-I catalogue that one of their premier razors is supposed to be made of this same melt of steel. Anyone ever run onto such a thing before? This is a nicely made razor with a file worked spine and jimping, no markings at all. I have seen older identical razors with T-I markings. I thought maybe with the barber's nose it was intended to be sold to a barber supply shop and etched with their name.
