I picked up this Tech the other day and I can't tell if it is Zamak or brass. I can't tell from the Mr Razor pictures and I don't have any other 3 piece razors to compare it to weight-wise. The 'Gillette' on the cap is very faded so I can't tell if it is etched or embossed. I apologize for such little to go off of, but can anyone tell me if this is brass? The handle seems heavy so I think at least that might be brass, but I'm not sure about the rest.
