Help identifying this British Gillette

[echelon3]

The only markings are an "S" and a "4" on the underside of the bottom plate, "Made in England" on the top of the bottom plate, and "Gillette" on the top of the top plate.
I don't have a magnet handy, but the handle feels like it's made of aluminum.
The razor appears unused.

My apologies for the iPhone photo quality.

Uh, and for not uploading the photos at first.

No picture to see yet but as you describe it you must have a Aluminum British Tech. Can't go wrong with that.

It´s a british Tech from 1972. It gives him with aluminum handel and with nickel plated handle:
