Who's "Ruby" and why would anybody want to take her home?

For all you .32 lovers, have I got a deal for you on gunbroker:

Forgive me, .32 lovers, but I just couldn't resist that last line of the auction description: "Revisit the WWI and WWII glories of the French army with this piece of military history."

That reminds me of the famous classified ad that appears in a Paris newspaper shortly after V-E Day in 1945: "For sale, French military rifle. Never fired. Dropped once. Cheap."
