The "Plus Ultra" was a variation on the Ruby automatic pistol made by Gabilondo y Urresti (the original holders of the Ruby trademark) just shortly before they changed their name to Llama. The Plus Ultra was a scaled-up Ruby using double stack, 22-round magazines (still chambered for .32ACP). It offered much greater capacity than the standard pistols, and a few were actually made as select-fire guns. They never sold particularly well, though, and are rather uncommon today.
