I was at the range the other day and noticed a shooter using a lever action single shot 12 gauge shotgun. I asked him what king of gun it was and he said it was a "Greeny". It operated like a single shot rifle: pulling down a polished handle in back of the trigger housing opened the chamber, pushing back the handle closed it. I googled the name "Greeny" shotgun and got no information. Has any one out there ever heard of it? Bill B.
