This beautiful antique safety razor was made in France, by Gillette. It is a “Tech” model, with open comb, three pieces with short screw, it uses standard safety razor blades (not included).
Its aluminum spiral handle has some oxidation marks, which will not interfere with shaving. The head is nickel-plated metal.
This Gillette Tech razor measures 8.2 cm for 35 grams.
The open-comb is a very rare version, I think it was only made for France.
