The brand is still used by Gillette for some of their Russian and Indian blades and razors.
Having never seen one, or had the opportunity to purchase a vintage one, I can't agree that the 7 O'clock razor is more common than a Gillette . . . at least not here in the States, anyway!
Was this a small company that Gillette purchased, or was it a brand name that they started in order to market against low-priced competition? (Like Rubie was.)
