I've got an English fat handled tech, does anyone know when these were made?
I was not saying that it was not authentic, just that I was not aware of an English-made Tech with such a handle. I would suspect that it was made in the 50s/60s. But it is hard to tell with the English ones. Generally, if they have the lighter aluminium handle, with a sort of criss-cross pattern, then they are from the 70s/80s.
