As far as I can tell, based on the word's use in advertising, RIGO was used by Richards from its start in 1912 right through to as late as the 1970s when the company was still calling its baby feeder nipples the "RIGO" brand.

There's another mark. (JR combo) "Rigo" script. That is on the base of machine made nurser bottles patented 1922 and des. 1926.ebay.com/itm/PAT-1922-DES-1926-RIGO-BABY-BOTTLE-NURSER-RIGO-NIPPLES-AD-BOTTLE-VENTED-8-OUNCE-[attachment=rigoscript.jpg]
