This is a highly detailed model of the Bushnell Turtle, America's first submarine. The model stands 18" tall and includes:
 
Two part hull (split at centerline)
Explosives barrel
Conning Tower hatch
snorkel
 
This would make an exceptionally unique RC model, or a very impressive static display. Parts are printed in PETG plastic for strength and durability. Hatch and snorkel are high definition resin.
