No
I would have to do some searching to verify this, but I don't believe Stevens ever made a shotgun using percussion caps.

Never heard of the maker.
Your weapon is not a flintlock but a percussion cap shotgun rifle made by GG Julcher of Philadelphia PA from c 1840 to the Civil War. It is an unusual weapon as the shotgun lock (Hammer and cap) on the left side is upside down, an extremely clumsy solution as the cap tends to fall off.

No. Some Percussion instruments are made of Metal like Copper,Brass,Iron,Steel, and etc. Some are even made of plastic and other materials.
I just purchased the same shot gun with a bird head handle.
The percussion cap was first invented by the Scotsman Reverend A Forsythe in 1803. His main reason for developing the system was to provide instant ignition to aid in the hunting of game birds (Forsyth was an avid duck hunter). His first percussion arm was of course a shotgun. Although patented in 1803 the percussion cap was not utilised on military arms for another 30 years.
