Two and three inch charging spoons are available from Conestoga Co., but the four inch spoon that the 16F uses was not available.
Being a tool & die maker, I made a die to bend the 4" spoon from a shape I snipped out of tin and later brass.
All originals will attract a magnet. Some of our 4" spoons were stamped "Ray-Vin".![]()

We cast silicon bronze ammo chests for the Big-Bang model 7D. These are easily distinguished from the originals with "RAY-VIN" marked on the bottom.
Also, the originals (being made from iron) will attract a magnet.
Ammo plugs were also reproed.
