London-made French “le Petit Protector du Fromage”
Manufactured by J. Hinds, English watchmaker and jeweler. 4mm pinfire six-round manually indexed cylinder, German silver band circled with blued steel hammer spring, no serial number of course as these were produced in the 20th century as one-off artificial curios. These gadgets would have been popular in the early 19th century, with the invention of self-contained cartridges by Frenchmen such as Casimir Lefaucheux making all sorts of weird firearms available to the discerning gentleman. Pinfire cartridges remain the ammunition of choice to this day when extremely small jeweler’s guns are concerned. The small protectors were the 4mm and 5mm version, but a 2mm alternative of this bauble also exist, named the “Femme Fatale” -le woman that kills you.
Manufactured in Great Britain c.late 20th century. ~4mm rocket ball, single shot, brass body and barrel. That’s an uncommon ring gun, among uncommon guns. The branding is still the same on these though, with a mix of fanciness and fake Frenchness.
