Not much is known about the brand Rio. There's a Rio coming from the Standard Safety Razor Corp, Wilmington Delaware, but the Compendium distinguishes that Rio from the Rio we have here: The Rio GL, that nobody knows anything about, and looks a lot like the TGM, that nobody knows anything about either.
Now I think that serie GL means it is a model, so there's the brand Rio, and the model GL, which could mean this Rio and the Delaware Rio are the same brand. Still a mystery though.
All plastic, except for the guard which is a metal spring.
