In the French army the skittle is a gift from your comrades of arm yo uget the day you get your honorable discharge. It is usually a hand crafted skittle, either wood or brass and on which could be added insignias and souvenirs fro mthe soldiers career. The Skittle (quille) stems from the ship ''la Quille'' which sailed home ex-convicts from Cayenne, French Guyanna home. So when you get the "quille" it means you served your time and that you are going home. The following are not from my own collection but taken from the internet and both modern and older samples.
